A plethora of long-range neutrino interactions probed by DUNE and T2HK
arxiv(2024)
摘要
Upcoming neutrino experiments will soon search for new neutrino interactions
more thoroughly than ever before, boosting the prospects of extending the
Standard Model. In anticipation of this, we forecast the capability of two of
the leading long-baseline neutrino oscillation experiments, DUNE and T2HK, to
look for new flavor-dependent neutrino interactions with electrons, protons,
and neutrons that could affect the transitions between different flavors. We
interpret their sensitivity in the context of long-range neutrino interactions,
mediated by a new neutral boson lighter than 10^-10 eV, and sourced by the
vast amount of nearby and distant matter in the Earth, Moon, Sun, Milky Way,
and beyond. For the first time, we explore the sensitivity of DUNE and T2HK to
a wide variety of U(1)^' symmetries, built from combinations of lepton
and baryon numbers, each of which induces new interactions that affect
oscillations differently. We find ample sensitivity: in all cases, DUNE and
T2HK may constrain the existence of the new interaction even if it is supremely
feeble, may discover it, and, in some cases, may identify the symmetry
responsible for it.
