چکیده

In a recently proposed extension of the Standard Model with a compact extra dimension of size R we compute the leading corrections, of relative order (mtR) 2, to the Branching Ratio BR(B → Xsγ). For R = (370 ± 80GeV )−1 the branching ratio is increased in a significant way relative to the SM, although not at the level of being inconsistent with present measurements.

Effects of the Electroweak Symmetry Breaking Sector in Rare B and K Decays

The effects of the electroweak symmetry breaking sector in rare B and K decays are considered in the presence of new strong dynamics at a large energy scale. In the context of the low energy effective lagrangian of the symmetry breaking sector, we focus on the contributions that are not constrained by bounds on oblique corrections or anomalous triple gauge boson vertices. We find that these hav...

∗ SLAC - PUB - 9277 July 2002

I discuss the theoretical and empirical status of b→ sγ, b→ sll decays, as well as their future prospects. I emphasize those observables in rare b-decays which can potentially establish new physics and distinguish between extensions of the Standard Model. I briefly review current models of electroweak symmetry breaking, all of which can carry interesting flavor characteristics accessible with b...

Phenomenological implications of moduli-dominant SUSY breaking

We study moduli-dominated SUSY breaking within the framework of string models. This type of SUSY breaking in general leads to non-universal soft masses, i.e. soft scalar masses and gaugino masses. Further gauginos are lighter than sfermions. This non-universality has phenomenologically important implications. We investigate radiative electroweak symmetry breaking in the mass spectrum derived fr...
