31. Coherent elastic neutrino nucleus scattering: experimental efforts at SNS and reactor-site

Janina Hakenmüller (Duke University)

5/19/23, 9:30 AM

Coherent elastic neutrino nucleus scattering (CE$\nu$NS) is a standard-model interaction in which the neutrino interacts with the nucleus as a whole. It was first measured by the COHERENT collaboration in 2017 decades after its prediction.
A coherent interaction is only possible at neutrino energies of a few tens of MeV or below, which makes the Spallation Neutron Source (SNS) at Oak Ridge...

9. Effective field theory approach for radiative corrections in neutron beta decay

Oleksandr Tomalak

5/19/23, 9:55 AM

We study radiative corrections to the neutron beta decay within the top-down effective field theory approach. First, we match the Standard Model to the four-fermion effective field theory specifying the scheme dependence of the Wilson coefficients. To evaluate radiative corrections at scales of the neutron decay, we perform matching to the heavy-baryon chiral perturbation theory for the vector...

26. Nuclear decay anomalies as a signature of axion dark matter

Tianjun Li

5/19/23, 10:20 AM

A number of nuclear decay anomalies have been reported in the literature, which purport to show periodic variations in the decay rates of certain radioisotopes. If these reports reflect reality, they would necessitate a seismic shift in our understanding of fundamental physics. We provide the first mechanism to explain these findings, via the misalignment mechanism of QCD axion dark matter,...
