$R_b$-$R_c$ Crisis and the Higgs Boson Mass from LEP Precision Data

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

We study the effects on the Higgs boson mass from LEP precision data of the new physics explaining RbR_b-RcR_c crisis. We implement a fit to LEP observables with the new physics. We obtain MHNewPhysics=8556+467  GeVM_H^{\rm New Physics} = 85 ^{+ 467}_{-56} ~~{\rm GeV}. Comparing with the value of the SM fit, MHSM=3821+96  GeVM_H^{\rm SM} = 38^{+ 96}_{-21} ~~{\rm GeV}, the errors are larger and the central value is higher. The new physics may allow MHM_H to have a value out of the range of O(MZ){\cal O}(M_Z).
