R_b Constraints on Littlest Higgs Model with T-parity
arXiv:0908.2572 · doi:10.1103/PhysRevD.80.055027
Abstract
In the framework of the littlest Higgs model with T-parity (LHT), we study the contributions of the T-even and T-odd particles to the branching ratio R_b. We find that the precision data of R_b can give strong constraints on the masses of T-odd fermions.
