Probing New Interactions with Neutron Beta Decay

GOAL: discover/constrain new BSM interactions originating at the TeV scale through snergy of:

1. Innovative precision measurements (10^-3 level) of neutron decay (n-->peV) at the LANL UCN source

2. Multi-scale theoretical analysis of BSM contributions to n decay: elucidate discovery potential and model discriminating power

The big picture: energy vs predicion frontier
Both direct (energy) and indirect (precision) probes will be needed to fully recnstruct the dynamics at the TeV scale

Theory Program

TeV scale: Analyze generation of new interactions (supersymmetry, extra dimensions, ...)
(Cirigliano, Graesser)

GeV scale: Calculate matrix elements (Lattice QCD, Chiral perturbation theory)
(Bhattacharya, Cirigliano, Gupta + PD)

Elucidate implications of neutron measurements for SM extensions, in the context of other precision measurements and collider searches (LHC)
