Differential, total, and cumulative cross section calculations for neutral current neutrino scattering on 128,130 Te isotopes are performed in the context of the quasiparticle random phase approximation by utilizing realistic twonucleon forces. These isotopes are the main contents of detectors of ongoing experiments with multiple neutrino physics goals (COBRA and CUORE at Gran Sasso), including potential low-energy astrophysical neutrino (solar, supernova, geoneutrinos) detection. The incoming neutrino energy range adopted in our calculations (ε ν 100 MeV) covers the low-energy β-beam neutrinos and the pion-muon stopped neutrino beams existing or planned to be conducted at future neutron spallation sources. The aim of these facilities is to measure neutrino-nucleus cross sections at low and intermediate neutrino energies with the hope of shedding light on open problems in neutrino-induced reactions on nuclei and neutrino astrophysics. Such probes motivate theoretical studies on weak responses of various nuclear systems; thus the evaluated cross sections may be useful in this direction. V. TSAKSTARA AND T. S.

“…This result indicates that the rate of µ − −e − conversion has a maximum around the medium nuclei (A ≈ 60), and flattens out or slightly decreases for heavy nuclei. However, the calculations, which took into account the nuclear effect, show a different Z dependence (Chiang, et al, 1993;Kosmas and Vergados, 1996;Kosmas, et al, 1998).…”

Muon decay and physics beyond the standard model

View full text Add to dashboard Cite

This article reviews the current theoretical and experimental status of the field of muon decay and its potential to search for new physics beyond the Standard Model. The importance of rare muon processes with lepton flavor violation is highly stressed, together with precision measurements of normal muon decay. Recent up-to-date motivations of lepton flavor violation based on supersymmetric models, in particular supersymmetric grand unified theories, are described along with other theoretical models. Future prospects of experiments and muon sources of high intensity for further progress in this field are also discussed.

Flavor in the Era of the LHC

View full text Add to dashboard Cite

This chapter of the report of the "Flavour in the era of the LHC" Workshop discusses the theoretical, phenomenological and experimental issues related to flavour phenomena in the charged lepton sector and in flavour-conserving CP-violating processes. We review the current experimental limits and the main theoretical models for the flavour structure of fundamental particles. We analyze the phenomenological consequences of the available data, setting constraints on explicit models beyond the Standard Model, presenting benchmarks for the discovery potential of forthcoming measurements both at the LHC and at low energy, and exploring options for possible future experiments.
