we present a determination of the neutral current weak axial charge $g^z_a(0)=-0.654(3)_{\rm stat}(5)_{\rm sys}$ using the strange quark axial charge $g^s_a(0)$ calculated with lattice qcd. we then perform a phenomenological analysis, where we combine the strange quark electromagnetic form factor from lattice qcd with ... | weak neutral current axial form factor using $(\\bar{\\nu})\\nu$-nucleon scattering and lattice qcd inputs |
charged-current neutrino-nucleus scattering is studied in the quasielastic region with various relativistic nuclear models that include the relativistic hartree, the nonlinear σ , the quark-meson coupling, and the chiral quark-meson coupling models. theoretical results at several kinematics are compared with experiment... | quasielastic charged-current neutrino-nucleus scattering with relativistic nuclear models |
neutral current quasielastic (anti)neutrino scattering cross sections on a 12c target are analyzed using a realistic spectral function s (p ,e ) that gives a scaling function in accordance with the (e ,e') scattering data. the spectral function accounts for the nucleon-nucleon (nn) correlations by using natural orbital... | neutral current quasielastic (anti)neutrino scattering beyond the fermi gas model at miniboone and bnl kinematics |
realistic nuclear structure calculations are presented for the event rates due to coherent elastic neutrino-nucleus scattering (ce ν ns ), assuming neutrinos from pion decay at rest, from nuclear reactors, and from earth's interior. we focus on the currently interesting germanium isotopes, 70,73,76ge, which constitute ... | coherent elastic neutrino-nucleus scattering (ce ν ns ) event rates for ge, zn, and si detector materials |
a core-collapse supernova (ccsn) provides a unique astrophysical site for studying neutrino-matter interactions. prior to the shock-breakout neutrino burst during the collapse of the iron core, a preshock νeburst arises from the electron capture of nuclei and it is sensitive to the low-energy coherent elastic neutrino-... | supernova preshock neutronization burst as a probe of nonstandard neutrino interactions |
a description of the current state of the project for the study of coherent elastic neutrino-atom scattering using a tritium source and liquid helium detector is given. the project was proposed in our paper in 2019 and its main goal is to obtain a new record limit on the neutrino magnetic moment at a level below 10^{-1... | a proposal for experiment with high-intensity tritium neutrino source in sarov: the search for coherent elastic neutrino-atom scattering and neutrino magnetic moment |
