A Stringy Solution to the FCNC Problem

Oleg Lebedev

The solution to the supersymmetric FCNC problem may not have a simple field theory interpretation. Here I advocate a possibility based on string selection rules. The requirement of…

Constraints on Gauged B-3L_tau and Related Theories

Lay Nam Chang, Oleg Lebedev, Will Loinaz +1

We consider extensions of the Standard Model with an extra U(1) gauge boson which couples to B-(alpha L_e + beta L_mu + gamma L_tau) with alpha + beta + gamma = 3. We show that the…

Constraints on R-parity Violation from Precision Electroweak Measurements

Tatsu Takeuchi, Oleg Lebedev, Will Loinaz

We constrain the size of R-parity violating couplings using precision electroweak data.

Constraining New Physics with Vertex Corrections

Tatsu Takeuchi, Oleg Lebedev, Will Loinaz

We discuss how new physics not encompassed within the STU oblique correction framework can be constrained from precision electroweak measurements via vertex corrections to Z-pole o…

Constraints on Two-Higgs Doublet Models at Large tan{beta} from W and Z decays

Oleg Lebedev, Will Loinaz, Tatsu Takeuchi

We study constraints on type-II two Higgs doublet models at large tan{beta} from LEP/SLD Z-pole data and from lepton universality violation in W decay. We perform a global fit and…

Constraints on R-parity violating couplings from LEP/SLD hadronic observables

Oleg Lebedev, Will Loinaz, Tatsu Takeuchi

We analyze the one loop corrections to hadronic Z decays in an R-parity violating extension to the Minimal Supersymmetric Standard Model (MSSM). Performing a global fit to all the…
