  Title Consistency of the Molecular Picture of Omega(2012) with the Latest Belle Results Type Journal Article
  Year 2023 Publication Few-Body Systems Abbreviated Journal Few-Body Syst.  
  Volume (down) 64 Issue 3 Pages 55 - 6pp  
  Keywords  
  Abstract We report the results of the research on the Omega(2012) state based on themolecular picture and discuss the consistency of the picture with the Belle experimental results. We study the interaction of the (K) over bar Xi*, eta Omega(s-wave) and (K) over bar Xi(d-wave) channels within a coupled channel unitary approach, and obtain the mass and the width of the Omega(2012) state and the decay ratio R-Xi(K) over bar(Xi pi(K) over bar). We also present a mechanism for Omega c -> pi(+)Omega(2012) production through an external emission Cabibbo favoredweak decay mode, where the Omega(2012) is dynamically generated from the above interaction. We find that the results obtained by the molecular picture are consistent with all Belle experimental data.

  Title Meson exchange between initial and final state and the R-D ratio in the B-bar -> D nu-bar l (nu_tau-bar tau) reactions Type Journal Article
  Year 2020 Publication European Physical Journal A Abbreviated Journal Eur. Phys. J. A  
  Volume (down) 56 Issue 2 Pages 73 - 12pp  
  Keywords  
  Abstract We perform a calculation of the strong interaction effects between the B and D mesons in the B -> D nu l reaction, as a crossing process of reactions with BD in the final state, where the strong interaction between the mesons leads to a bound BD state. We find corrections to the tree level amplitude of the order of 15-25%. We further see the effect of the corrections studied in the R-D ratio for the rates of B -> D nu and B. D decays and find corrections of the order of 10%. Given the claims of 1.5% precision in this ratio from fits to data within the standardmodel, any theoretical model aiming at describing this ratio within the same precision must take into account the corrections described in the present work.

  Title Sequential single pion production explaining the dibaryon “d*(2380)” peak Type Journal Article
  Year 2023 Publication Chinese Physics C Abbreviated Journal Chin. Phys. C  
  Volume (down) 47 Issue 4 Pages 041001 - 10pp  
  Keywords dibaryon; sequential mechanism; explanation  
  Abstract In this study, we investigate the two step sequential one pion production mechanism, that is, np(I=0)->pi(-)pp followed by the fusion reaction pp ->pi(+)d, to describe the np ->pi(+)pi(-)d reaction with in state I = 0 . In this reaction, a narrow peak identified with a “ d(2380) ” dibaryon has been previously observed. We discover that the second reaction step pp ->pi(+)d is driven by a triangle singularity that determines the position of the peak of the reaction and the high strength of the cross section. The combined cross section of these two mechanisms produces a narrow peak with a position, width, and strength, that are compatible with experimental observations within the applied approximations made. This novel interpretation of the peak accomplished without invoking a dibaryon explains why this peak has remained undetected in other reactions.
