- Probing TeV scale physics in ultra-cold neutron decays
- Time: 2:30 pm - 3:30 pm
- Place: 4274 Chamberlin
- Speaker: Rajan Gupta, Los Alamos National Laboratory
- Abstract: This talk will describe the possibility of probing scalar and tensor interactions
arising from new physics at the TeV scale at the two experiments, UCNb
and UCNB, being developed at the ultra-cold neutron source at Los Alamos.
I will show that the largest uncertainty is connecting theory to experiments
(with measurements at the 10^{-3} level), comes from estimates of the
scalar and tensor charges of a nucleon. I will then discuss the status of our lattice
QCD calculations of these matrix elements and plans for the future. As summary, a
discussion of current bounds on these novel interactions will be presented.
