Open system approach to neutrinos propagating in an ultralight scalar background
Lua F. T. Airoldi, Gustavo F. S. Alves, Pedro A. N. Machado +1
We examine decoherence in neutrino oscillations induced by an ultralight scalar field coupled to neutrinos. The scalar induces time- and position-dependent shifts in the neutrino m…
The correction to superallowed beta decays in effective field theory and implications for
Zehua Cao, Richard J. Hill, Ryan Plestid +1
Superallowed () beta decays currently provide the most precise extraction of quark mixing in the Standard Model. Their interpretation as a measurement of $|V_{ud…
Factorization and resummation of QED radiative corrections for neutron beta decay
Zehua Cao, Richard J. Hill, Ryan Plestid +1
Details of the two-loop analysis of long-distance QED radiative corrections to neutron beta decay are presented. Explicit expressions are given for hard, jet, and soft functions ap…
Bottomonium suppression in pNRQCD and open quantum system approach
Ajaharul Islam, Nora Brambilla, Miguel Ãngel Escobedo +3
By employing the potential non-relativistic quantum chromodynamics (pNRQCD) effective field theory within an open quantum system framework, we derive a Lindblad equation governing…
