Cross Sections of Charged Current Neutrino Scattering off¹³²Xe for the Supernova Detection

Abstract

The total cross sections as well as the neutrino event rates are calculated in the charged current neutrino and antineutrino scattering off132Xe isotope at neutrino energiesEv<100 MeV. Transitions to excited nuclear states are calculated in the framework of quasiparticle random-phase approximation. The contributions from different multipoles are shown for various neutrino energies. Flux-averaged cross sections are obtained by convolving the cross sections with a two-parameter Fermi-Dirac distribution. The flux-averaged cross sections are also calculated using terrestrial neutrino sources based on conventional sources (muon decay at rest) or on low-energy beta-beams.

Charged-current neutrino-nucleus scattering off Xe isotopes

“…Charged-current scattering of neutrinos off 132 Xe was also previously calculated in a similar formalism in Ref. [19]. Similar calculations for Cd and Mo nuclei have been carried out in Refs.…”

“…Cross sections for the A = 132 case have been calculated in the pnQRPA formalism in Ref. [19]. The cross sections obtained in Ref.…”

“…Earlier calculations of charged-current neutrino-nucleus scattering cross sections have been carried out for various nuclei in the nuclear shell model [11][12][13][14][15][16], proton-neutron quasiparticle random-phase approximation (pnQRPA) with realistic effective interactions [17][18][19][20][21], pnQRPA based on Skyrme forces [12,[22][23][24], pnQRPA with neutron-proton pairing [25][26][27], a consistent relativistic mean-field approach [28], a hybrid model combining shell model for the allowed transitions and pnQRPA for forbidden transitions [29][30][31], and the microscopic quasiparticle-phonon model (MQPM) [21,32]. In the present work we compute cross sections of neutrinos and antineutrinos scattering off 128 Xe, 129 Xe, 130 Xe, 131 Xe, 132 Xe, 134 Xe, and 136 Xe via charged-current processes in the microscopic nuclear frameworks of pnQRPA for the even-mass nuclei and MQPM for the odd-mass nuclei.…”

Neutrino Interactions with Nuclei and Dark Matter

“…The nuclear matrix elements entering in Eqs. (8) and (9) have been calculated in the framework of pnQRPA [73][74][75]. The respective cross sections are listed in Tables 1 and 2 for various incoming (anti)neutrino energies E ν below 100 MeV.…”

Detectability of galactic supernova neutrinos coherently scattered on xenon nuclei in XMASS

“…Neutrino-electron neutral current scatterings (ν + e − → ν + e − ) and neutrino-nucleus quasi-elastic scatterings are other possible observation channels. However, their cross sections are orders of magnitude smaller than that of coherent scatterings [22][23][24][25][26][27], and will not be discussed in this work.…”
