  Title Search for CP violation using T-odd correlations in D-0 -> K+K-pi(+)pi(-) decays Type Journal Article
  Year 2014 Publication Journal of High Energy Physics Abbreviated Journal J. High Energy Phys.  
  Volume 10 Issue (up) 10 Pages 005 - 21pp  
  Keywords CP violation; Charm physics; Hadron-Hadron Scattering; Flavor physics  
  Abstract A search for CP violation using T-odd correlations is performed using the four-body D-0 -> K+K-pi(+)pi(-) decay, selected from semileptonic B decays. The data sample corresponds to integrated luminosities of 1.0 fb(-1) and 2.0 fb(-1) recorded at the centre-of-mass energies of 7 TeV and 8 TeV, respectively. The CP-violating asymmetry alpha(T-odd)(CP) is measured to be (0.18 +/- 0.29 (stat) +/- 0.04 (syst))%. Searches for CP violation in different regions of phase space of the four-body decay, and as a function of the D-0 decay time, are also presented. No significant deviation from the CP conservation hypothesis is found.

  Title Measurement of the time-integrated CP asymmetry in D-0 -> (KSKS0)-K-0 decays Type Journal Article
  Year 2015 Publication Journal of High Energy Physics Abbreviated Journal J. High Energy Phys.  
  Volume 10 Issue (up) 10 Pages 055 - 15pp  
  Keywords CP violation; Charm physics; Flavor physics; Hadron-Hadron Scattering  
  Abstract The time-integrated CP asymmetry in the decay D-0 -> (KSKS0)-K-0 is measured using 3 fb(-1) of proton-proton collision data collected by the LHCb experiment at centreof- mass energies of 7 and 8TeV. The flavour of the D-0 meson is determined by use of the decay D*(+) -> D-0 pi(+) and its charge conjugate mode. The result is A(CP) = -0.029 +/- 0.052 +/- 0.022, where the first uncertainty is statistical and the second systematic. The result is consistent with Standard Model expectations and improves the uncertainty with respect to the only previous measurement of this quantity by more than a factor of three.

  Title Study of prompt D-0 meson production in pPb collisions at root(NN)-N-s=5 TeV Type Journal Article
  Year 2017 Publication Journal of High Energy Physics Abbreviated Journal J. High Energy Phys.  
  Volume 10 Issue (up) 10 Pages 090 - 28pp  
  Keywords Charm physics; Heavy Ion Experiments; Heavy-ion collision; Particle and resonance production  
  Abstract Production of prompt D-0 mesons is studied in proton-lead and lead-proton collisions recorded at the LHCb detector at the LHC. The data sample corresponds to an integrated luminosity of 1.58 +/- 0.02 nb(-1) recorded at a nucleon-nucleon centre-of-mass energy of root(NN)-N-s = 5 TeV. Measurements of the differential cross-section, the forward-backward production ratio and the nuclear modification factor are reported using D-0 candidates with transverse momenta less than 10 GeV/c and rapidities in the ranges 1.5 < y* < 4.0 and -5.0 < y* < -2.5 in the nucleon-nucleon centre-of-mass system.

  Title Central exclusive production of J/psi and (2S) mesons in pp collisions at root s=13 TeV Type Journal Article
  Year 2018 Publication Journal of High Energy Physics Abbreviated Journal J. High Energy Phys.  
  Volume 10 Issue (up) 10 Pages 167 - 27pp  
  Keywords Charm physics; Forward physics; Hadron-Hadron scattering (experiments); Particle and resonance production; Quarkonium  
  Abstract Measurements are reported of the central exclusive production of J= and ( 2 S) mesons in pp collisions at a centre- of- mass energy of 13 TeV. Backgrounds are signi fi cantly reduced compared to previous measurements made at lower energies through the use of new forward shower counters. The products of the cross- sections and the branching fractions for the decays to dimuons, where both muons are within the pseudorapidity range 2 : 0 < < 4 : 5, are measured to be The fi rst uncertainties are statistical, the second are systematic, and the third are due to the luminosity determination. The cross- sections are also measured di ff erentially for meson rapidities between 2.0 and 4.5. Good agreement is observed with theoretical predictions. Photoproduction cross- sections are derived and compared to previous experiments, and a deviation from a pure power- law extrapolation of lower energy data is observed.

  Title A search for Xi(++)(cc) -> D(+)pK(-)pi(+) decays Type Journal Article
  Year 2019 Publication Journal of High Energy Physics Abbreviated Journal J. High Energy Phys.  
  Volume 10 Issue (up) 10 Pages 124 - 21pp  
  Keywords Branching fraction; Charm physics; Hadron-Hadron scattering (experiments)  
  Abstract A search for the Xi(++)(cc) baryon through the Xi(++)(cc) -> D(+)pK(-)pi(+) decay is performed with a data sample corresponding to an integrated luminosity of 1.7 fb(-1) recorded by the LHCb experiment in pp collisions at a centre-of-mass energy of 13 TeV. No significant signal is observed in the mass range from the kinematic threshold of the decay to 3800 MeV/c(2). An upper limit is set on the ratio of branching fractions R = B(Xi(++)(cc) -> D(+)pK(-)pi(+))/B(Xi(++)(cc) -> A(c)(+) K- pi(+)pi(+)) with R < 1.7 (2.1) x 10(-2) at the 90% (95%) confidence level at the known mass of the Xi(++)(cc) state.

  Title Measurement of the time-integrated CP asymmetry in D (0) -> K (S) (0) K (S) (0) decays Type Journal Article
  Year 2018 Publication Journal of High Energy Physics Abbreviated Journal J. High Energy Phys.  
  Volume 11 Issue (up) 11 Pages 048 - 19pp  
  Keywords Charm physics; CP violation; Flavor physics; Hadron-Hadron scattering (experiments)  
  Abstract A measurement of the time-integrated CP asymmetry in D (0) -> K (S) (0) K (S) (0) decays is reported. The data correspond to an integrated luminosity of about 2 fb(-1) collected in 2015-2016 by the LHCb collaboration in pp collisions at a centre-of-mass energy of 13 TeV. The D (0) candidate is required to originate from a D (*+) -> D (0) pi (+) decay, allowing the determination of the flavour of the D (0) meson using the pion charge. The D (0) -> K (+) K (-) decay, which has a well measured CP asymmetry, is used as a calibration channel. The CP asymmetryfor D (0) -> K (S) (0) K (S) (0) is measured to be where the first uncertainty is statistical and the second is systematic. This result is combined with the previous LHCb measurement at lower centre-of-mass energies to obtain A(CP) (D-0 -> K-S(0) K-S(0)) = (2.3 +/- 2.8 +/- 0.9)%.

  Title Search for the doubly charmed baryon Xi(+)(cc) in the Xi(+)(c)pi(-)pi(+) final state Type Journal Article
  Year 2021 Publication Journal of High Energy Physics Abbreviated Journal J. High Energy Phys.  
  Volume 12 Issue (up) 12 Pages 107 - 27pp  
  Keywords Charm physics; Hadron-Hadron scattering (experiments); Branching fraction; QCD; Flavor physics  
  Abstract A search for the doubly charmed baryon Xi(+)(cc) is performed in the Xi(+)(c)pi(-)pi(+ )invariant-mass spectrum, where the Xi(-)(cc) baryon is reconstructed in the pK(-)pi(+) final state. The study uses proton-proton collision data collected with the LHCb detector at a centreof-mass energy of 13 TeV, corresponding to a total integrated luminosity of 5.4 fb(-1). No significant signal is observed in the invariant-mass range of 3.4-3.8 GeV/c(2). Upper limits are set on the ratio of branching fractions multiplied by the production cross-section with respect to the Xi(++)(cc) -> (Xi(+)(c) -> pK(-)pi(+)+/-)pi(+ ) decay for different Xi(+)(cc) mass and lifetime hy- potheses in the rapidity range from 2.0 to 4.5 and the transverse momentum range from 2.5 to 25 GeV/c. The results from this search are combined with a previously published search for the Xi(+)(cc) -> A(c)(+)K(-)pi(+ ) decay mode, yielding a maximum local significance of 4.0 standard deviations around the mass of 3620 MeV/c(2), including systematic uncertainties. Taking into account the look-elsewhere effect in the 3.5-3.7 GeV/c(2) mass window, the combined global significance is 2.9 standard deviations including systematic uncertainties.

  Title Simultaneous determination of CKM angle gamma and charm mixing parameters Type Journal Article
  Year 2021 Publication Journal of High Energy Physics Abbreviated Journal J. High Energy Phys.  
  Volume 12 Issue (up) 12 Pages 141 - 32pp  
  Keywords B physics; Charm physics; CKM angle gamma; CP violation; Hadron-Hadron scattering (experiments)  
  Abstract A combination of measurements sensitive to the CP violation angle gamma of the Cabibbo-Kobayashi-Maskawa unitarity triangle and to the charm mixing parameters that describe oscillations between D-0 and (D) over bar (0) mesons is performed. Results from the charm and beauty sectors, based on data collected with the LHCb detector at CERN's Large Hadron Collider, are combined for the first time. This method provides an improvement on the precision of the charm mixing parameter y by a factor of two with respect to the current world average. The charm mixing parameters are determined to be x = (0.400(-0.053)(+0.052))% and y = (0.630(-0.030)(+0.033))%. The angle gamma is found to be gamma = (65.4(-4.2)(+3.8))degrees and is the most precise determination from a single experiment.

  Title Study of D-(*())(+)(sJ) mesons decaying to D*K-+(S)0 and D*K-0(+) final states Type Journal Article
  Year 2016 Publication Journal of High Energy Physics Abbreviated Journal J. High Energy Phys.  
  Volume 02 Issue (up) 2 Pages 133 - 26pp  
  Keywords Hadron-Hadron scattering; Charm physics  
  Abstract A search is performed for D-sJ(()*()+) mesons in the reactions pp -> D*(+KSX)-X-0 and pp -> D*(K+X)-K-0 using data collected at centre-of-mass energies of 7 and 8 TeV with the LHCb detector. For the D*K-+(S)0 final state, the decays D*(+) -> D-0 pi(+) with D-0 -> K-pi(+) and D-0 -> K-pi(+)pi(+)pi(-) are used. For D*K-0(+), the decay D*(0) -> D-0 pi(0) with D-0 -> K-pi(+) is used. A prominent D-s1(2536)(+) signal is observed in both D*K-+(S)0 and D*K-0(+) final states. The resonances D*(s1)(2700)(+) and D*(s3)(2860)(+) are also observed, yielding information on their properties, including spin-parity assignments. The decay D*(s2)(2573)(+) -> D*(+) K-S(0) is observed for the first time, at a significance of 6.9 sigma, and its branching fraction relative to the D*(s2)(2573)(+) -> (D+KS0) decay mode is measured.
