the connie experiment (coherent neutrino nucleus interaction experiment) is currently collecting reactor neutrino data to search for the undiscovered standard model process of coherent neutrino-nucleus scattering (cnns). the detector is composed of a silicon target of thick, fully-depleted, low-noise ccd detectors. res... | results from 2015 and the 2016 upgrade of the connie experiment for detecting coherent neutrino nucleus scattering |
the mössbauer spectroscopy is proposed as an alternative experimental technique to be pursued in the detection of coherent elastic ν-nucleus scattering (cenns). the neutrino transferred energy in the neutrino-nucleus interaction causes a perturbation at the nuclear level structure of the mössbauer isotope, leading to a... | searching signature of neutrino-nucleus coherent scattering with mössbauer spectroscopy |
comet (coherent muon to electron transition, j-parc, japan) is one of the experiments that studies extensions of the standard model (sm) of elementary particle physics. the main purpose of the comet experiment is to search for charged lepton flavor violating neutrinoless conversion of muons into electrons in the field ... | properties of straw tubes for the tracking detector of the comet experiment |
we investigated the in-medium effect by density-dependent axial and weak-vector form factors on muon-neutrino ({{ν }μ }) and anti-muon-neutrino ({{\bar{ν }}μ }) scattering in the quasi-elastic (qe) region from nucleons (n*) bound in a nucleus or immersed in a nuclear medium via neutral current (nc) and charged current ... | in-medium effect with muon-neutrino and anti-muon-neutrino quasi-elastic scattering from 12c nucleons |
