the dynamic linear response of a quantum system is critical for understanding both the structure and dynamics of strongly-interacting quantum systems, including neutron scattering from materials, photon and electron scattering from atomic systems, and electron and neutrino scattering by nuclei. we present a general alg... | linear response on a quantum computer |
the connie experiment uses fully depleted, high resistivity ccds as particle detectors in an attempt to measure for the first time the coherent neutrino-nucleus elastic scattering of antineutrinos from a nuclear reactor with silicon nuclei.this talk, given at the xv mexican workshop on particles and fields (mwpf), disc... | the connie experiment |
charged-current neutrino-nucleus scattering is studied in the quasielastic region with the kids (korea-ibs-daegu-skku) nuclear energy density functional. we focus on the uncertainties stemming from the axial mass and the in-medium effective mass of the nucleon. comparing the result of theory to the state-of-the-art dat... | quasielastic charged-current neutrino-nucleus scattering with nonrelativistic nuclear energy density functionals |
in several extensions of the standard model of particle physics (smpp), the neutrinos acquire electromagnetic properties such as the electric millicharge. theoretical and experimental bounds have been reported in the literature for this parameter. in this work, we first carried out a statistical analysis by using data ... | constraints on neutrino electric millicharge from experiments of elastic neutrino-electron interaction and future experimental proposals involving coherent elastic neutrino-nucleus scattering |
the search for coherent elastic neutrino nucleus scattering (ce$\nu$ns) using reactor antineutrinos represents a formidable experimental challenge, recently boosted by the observation of such a process at the dresden-ii reactor site using a germanium detector. this observation relies on an unexpected enhancement at low... | on the impact of the migdal effect in reactor ce$\\nu$ns experiments |
the paleoccene concept offers the potential for room-temperature, passive and robust detectors in the gram to kilogram range for the detection of low-energy nuclear recoil events. nuclear recoil events can be caused by neutron scattering, coherent elastic neutrino nucleus scattering (cevns) or dark matter scattering an... | passive low energy nuclear recoil detection with color centers -- paleoccene |
we consider a scenario where an su(2) triplet scalar acts as the portal for a scalar dark matter particle. we identify regions of the parameter space, where such a triplet coexists with the usual higgs doublet consistently with all theoretical as well as neutrino, accelerator and dark matter constraints, and the triple... | lhc signals of triplet scalars as dark matter portal: cut-based approach and improvement with gradient boosting and neural networks |
distinguishing a dark matter interaction from an astrophysical neutrino-induced interaction will be major challenge for future direct dark matter searches. in this paper, we consider this issue within nonrelativistic effective field theory (eft), which provides a well-motivated theoretical framework for determining nuc... | effective field theory treatment of the neutrino background in direct dark matter detection experiments |
