CP violating anomalous top-quark couplings at the Large Hadron Collider
Sudhir Kumar Gupta
In this talk, I review the T-odd correlations induced by CP violating anomalous top-quark couplings at both production and decay level in the process gg --> t t_bar --> (b mu+ nu_m…
Penguin and Box Diagrams in Unitary Gauge
Xiao-Gang He, Jusak Tandean, G. Valencia
We evaluate one-loop diagrams in the unitary gauge that contribute to flavor-changing neutral current (FCNC) transitions involving two and four fermions. Specifically, we deal with…
Ansatz for small FCNC with a non-universal
Xiao-Gang He, German Valencia
It is well known that a non-universal induces tree-level FCNC which are severely constrained by experiment, most notably meson mixing. We point out that there is a class…
CP violating anomalous top-quark couplings at the LHC
Sudhir Kumar Gupta, Alaettin Serhan Mete, G. Valencia
We study the T odd correlations induced by CP violating anomalous top-quark couplings at both production and decay level in the process gg --> t t_bar --> (b mu+ nu_mu) (b_bar mu-…
Probing New Physics in Charm Couplings with FCNC
Xiao-Gang He, Jusak Tandean, G. Valencia
Low-energy experiments involving kaon, B-meson, D-meson, and hyperon flavor-changing neutral transitions have confirmed the loop-induced flavor-changing neutral current (FCNC) pict…
