In this paper we derive an exact master equation for two coupled quantum harmonic oscillators interacting via bilinear coupling with a common environment at arbitrary temperature made up of many harmonic oscillators with a general spectral density function. We first show a simple derivation based on the observation that the two harmonic oscillator model can… (More)

We calculate the dominant contributions to the muon g−2 at the two-loop level due to a generic pseudoscalar boson that may exist in any exotic Higgs sector in most extensions of the standard model. The leading effect comes from diagrams of the Barr-Zee type. A sufficiently light pseudoscalar Higgs boson can give rise to contribution as large as the… (More)

The recent measurement of the muon anomalous magnetic moment aμ shows a 2.6σ deviation from the standard model value. We show that it puts strong constraints on the parameter space of the two-Higgs doublet model (2HDM) II. The dominant contribution of the Higgs bosons comes at the two-loop level, and in order to explain the data it favors a pseudoscalar A… (More)

In the gauge-mediated supersymmetry breaking models with scalar tau as the next-to-lightest supersymmetric particle, a scalar lepton may decay dominantly into its superpartner, tau lepton, and the lightest scalar tau particle through l̃ → lτ±τ̃ 1 . We give detailed formulas for the three-body decay amplitudes and the polarization asymmetry of the outgoing… (More)

There are many mechanisms of obtaining CP violation if one starts from a CP conserving higher dimensional theory[1, 2]. The idea is not new. For example, Thirring considered such possibility as early as 1972[1]. Recently, with the renewed interest in the extra dimensional theories due to many new approaches to the additional dimensions, new schemes of… (More)

We demonstrate that the R-parity breaking interactions within their current experimental upper bounds can give rise to large mixing-induced CP asymmetry in exclusive radiative B decays that may be detectable in the upcoming B factories. PACS number(s): 11.30.Er, 13.25.Hw, 12.60.Jv, 11.30.Fs

Canonical quantization of spherically symmetric initial data which is appropriate to classical interior black hole solutions in four dimensions is carried out and solved exactly without gauge fixing. The resultant mini-superspace manifold and arena for quantum geometrodynamics is twodimensional, of signature (+,−), non-singular, and can in fact be… (More)
