Low Energy Searches for BSM Physics
We present a search for the non-conservation of lepton flavor in the
decay tau -> mu/e gamma performed with 967 M tau decays from e+e-
annihilations collected by the BABAR detector at the PEP-II storage
ring at a center-of-mass energy corresponding to Y(2S), Y(3S) and
Y(4S) resonances.

Low Energy Searches for BSM Physics
Charged lepton-flavor violating (CLFV) processes are extremely rare in
the Standard Model, but they may occur in various beyond-the-Standard
Model (BSM) theories, including SUSY or models with leptoquarks or
compositeness. We present a search CLFV decays Upsilon --> e+ tau- and
Upsilon --> mu+ tau- which probes BSM contributions at the TeV
mass scales.

Low Energy Searches for BSM Physics
We study, in a model-independent analysis, the possibility of direct detection of light fermionic dark matter in neutrino experiments. We consider all operators of dimension six or lower which can contribute to the process f p -> n e+, where f is a dark fermion, and place constraints on their coefficients via the dark matter lifetime. We then discuss limits on these interactions from...

Low Energy Searches for BSM Physics
The Spallation Neutron Source in Oak Ridge, Tennessee, is designed to produce intense pulsed neutrons for various science and engineering applications. Copious neutrinos are a free by-product. When it reaches full power in 2009, the SNS will be the world's brightest source of neutrinos in the few tens of MeV range. The proposed CLEAR (Coherent Low Energy A (Nuclear) Recoils) experiment...

Low Energy Searches for BSM Physics
In many models of physics beyond the Standard Model, it is necessary to suppress new, large sources of flavor-changing neutral currents. One recipe is to demand that the new physics exhibits “minimal flavor violation.” Though this is really a constraint on the quark sector of the theory, it can have strong effects on possible sources of lepton number violation. In particular, it strongly...

Low Energy Searches for BSM Physics
The Mu2e collaboration is proposing to search for coherent, neutrino-less conversion of muons into electrons in the field of a nucleus with a sensitivity improvement of approximately 10,000 over existing limits. Such a lepton flavor-violating reaction probes new physics at a scale unavailable by direct searches at either present or planned high energy colliders. The physics motivation for Mu2e...

Low Energy Searches for BSM Physics
We demonstrate that in effective theories arising from ${\cal N}=1$ fluxless compactifications of M-theory on a $G_2$ manifold with low energy supersymmetry, CP-violating phases do not appear in the soft-breaking Lagrangian except via the Yukawas. Such a mechanism may be present in other string compactifications as well; we describe properties sufficient for this to occur. CP violation is...
