Title Nonunitarity of the lepton mixing matrix at the European Spallation Source Type Journal Article
Year 2022 Publication (up) Physical Review D Abbreviated Journal Phys. Rev. D
Volume 106 Issue 7 Pages 075016 - 16pp
Keywords
Abstract If neutrinos get mass through the exchange of lepton mediators, as in seesaw schemes, the neutrino appearance probabilities in oscillation experiments are modified due to effective nonunitarity of the lepton mixing matrix. This also leads to new CP phases and an ambiguity in underpinning the “conventional” phase of the three-neutrino paradigm. We study the CP sensitivities of various setups based at the European Spallation Source neutrino super-beam (ESSnuSB) experiment in the presence of nonunitarity. We also examine its potential in constraining the associated new physics parameters. Moreover, we show how the combination of DUNE and ESSnuSB can help further improve the sensitivities on the nonunitarity parameters.

Title Constraining nonstandard interactions with coherent elastic neutrino-nucleus scattering at the European Spallation Source Type Journal Article
Year 2023 Publication (up) Physical Review D Abbreviated Journal Phys. Rev. D
Volume 107 Issue 5 Pages 055019 - 17pp
Keywords
Abstract The European Spallation Source (ESS), currently under construction in Sweden, will provide an intense pulsed neutrino flux allowing for high-statistics measurements of coherent elastic neutrino-nucleus scattering (CEvNS) with advanced nuclear recoil detectors. In this paper, we investigate in detail the possibility of constraining nonstandard neutrino interactions (NSIs) through such precision CEvNS measurements at the ESS, considering the different proposed detection technologies, either alone or in combination. We first study the sensitivity to neutral-current NSI parameters that each detector can reach in 3 years of data taking. We then show that operating two detectors simultaneously can significantly improve the expected sensitivity on flavor-diagonal NSI parameters. Combining the results of two detectors turns out to be even more useful when two NSI parameters are assumed to be nonvanishing at a time. In this case, suitably chosen detector combinations can reduce the degeneracies between some pairs of NSI parameters to a small region of the parameter space.

Title Testing the nonunitarity of the leptonic mixing matrix at FASERv and FASERv2 Type Journal Article
Year 2024 Publication (up) Physical Review D Abbreviated Journal Phys. Rev. D
Volume 109 Issue 1 Pages L011705 - 6pp
Keywords
Abstract The FASERv experiment has detected the first neutrino events coming from LHC. Near future highstatistic neutrino samples will allow us to search for new physics within the neutrino sector. Motivated by the forthcoming promising FASERv neutrino data, and its successor, FASERv2, we study its potential for testing the unitarity of the neutrino lepton mixing matrix. Although it would be challenging for FASERv and FASERv2 to have strong constraints on this kind of new physics, we discuss its role in contributing to a future improved global analysis.

Title Leptonic neutral-current probes in a short-distance DUNE-like setup Type Journal Article
Year 2024 Publication (up) Physical Review D Abbreviated Journal Phys. Rev. D
Volume 109 Issue 11 Pages 115007 - 12pp
Keywords
Abstract Precision measurements of neutrino -electron scattering may provide a viable way to test the nonminimal form of the charged and neutral current weak interactions within a hypothetical near -detector setup for the Deep Underground Neutrino Experiment (DUNE). Although low -statistics, these processes are clean and provide information complementing the results derived from oscillation studies. They could shed light on the scale of neutrino mass generation in low -scale seesaw schemes.

Title New Ambiguity in Probing CP Violation in Neutrino Oscillations Type Journal Article
Year 2016 Publication (up) Physical Review Letters Abbreviated Journal Phys. Rev. Lett.
Volume 117 Issue 6 Pages 061804 - 5pp
Keywords
Abstract If neutrinos get mass via the seesaw mechanism the mixing matrix describing neutrino oscillations can be effectively nonunitary. We show that in this case the neutrino appearance probabilities involve a new CP phase phi associated with nonunitarity. This leads to an ambiguity in extracting the “standard” three-neutrino phase delta(CP), which can survive even after neutrino and antineutrino channels are combined. Its existence should be taken into account in the planning of any oscillation experiment aiming at a robust measurement of delta(CP).
