Constraining the flavor changing Higgs couplings to the top-quark at the LHC
David Atwood, Sudhir Kumar Gupta, Amarjit Soni
We study the flavor-changing couplings of the Higgs-boson with the top-quark using the processes: (a) pp --> tt, (b) pp --> t_bar j, and, (c) pp --> t_bar j h at the LHC in light o…
Same-sign Tops: A Powerful Diagnostic Test for Models of New Physics
David Atwood, Sudhir Kumar Gupta, Amarjit Soni
We study the connection between the same sign top (SST) and the top quark forward-backward asymmetry . We find that a large class of new physics models that have been pro…
Searching for the Origin of CP violation in Cabibbo Suppressed D-meson Decays
David Atwood, Amarjit Soni
The recent evidence of large direct CP violation in D0 decay at LHCb suggests that such CP studies may become an important avenue for understanding CP. In this paper, we make sever…
Detecting Fourth Generation Quarks at Hadron Colliders
David Atwood, Sudhir Kumar Gupta, Amarjit Soni
We consider the phenomenology of the fourth generation heavy quarks which would be pair produced at the LHC. We show that if such a quark with a mass in the phenomenologically inte…
Probing Randall-Sundram Model using triphotons at the LHC
David Atwood, Sudhir Kumar Gupta
We investigate triphoton signals of the Randall-Sundram model at the Large Hadron Collider. Such a signal can be an important probe to the RS model as these are relatively cleaner…
Measuring Bs Width Difference at the Upsilon(5s) Using Quantum Entanglement
David Atwood, Amarjit Soni
About 90% of Bs-bar Bs pairs produced at the Upsilon(5s) resonance are initially Bs*-bar Bs* pairs which decay radiatively to Bs-bar Bs. This implies that the Bs pair will then be…
