Flavor-changing decay h → τ μ at super hadron colliders

Flavor Changing Neutral Currents at μ + μ − Colliders

We illustrate the possibility of observing signals from Flavor Changing Neutral Currents, originating from the scalar sector of a Two Higgs Doublet Model. In particular, we focus on the tree level process µ + µ − → ¯ tc + ¯ ct, via scalar exchange in the s-channel, as a distinctive process for µ + µ − colliders.

Top-Quark Decay Via Flavor-Changing Neutral Currents at Hadron Colliders

We study low energy experimental constraints on an anomalous top-quark coupling associated with the flavor-changing neutral current vertex Zt̄c. In view of these constraints, we discuss the experimental observability of the induced rare decay mode t → Zc, both at the Fermilab Tevatron (with the Main Injector or a luminosity-upgrade) and at the LHC.

Electroweak and Flavor Dynamics at Hadron Colliders

We catalog the principal signatures of electroweak and flavor dynamics at p̄p and pp colliders for use at the 1996 Snowmass Workshop on New Directions in High Energy Physics. The framework for dynamical symmetry breaking we assume is technicolor, with a walking coupling αTC , and extended technicolor. The reactions discussed occur mainly at subprocess energies √ ŝ <∼ 1TeV. They include productio...

Flavor changing scalar couplings and tγ(Z) production at hadron colliders

We calculate the contributions of the flavor changing scalar (FCS) couplings arised from topcolor-assisted technicolor (TC2) models at tree-level to the tγ and tZ production at the Tevatron and LHC experiments. We find that the production cross sections are very small at the Tevatron with √ s = 1.96TeV , which is smaller than 5 fb in most of the parameter space of TC2 models. However, the virtu...
