Higgs: Standard Model and Beyond

open access: yes, 2002
In this talk, I will discuss possible new physics effects that modify the interaction of Higgs boson(s) with top and bottom quarks, and discuss how to detect such effects in current and future high energy colliders.Comment: LaTeX, 8 pages including 1 ...

Search for physics beyond the standard model in high-mass diphoton events from proton-proton collisions at $\sqrt{s} =$ 13 TeV [PDF]

open access: yes, 2018
A search for physics beyond the standard model is performed using a sample of high-mass diphoton events produced in proton-proton collisions at $\sqrt{s} = $ 13 TeV.

Ultraviolet completion of a composite asymmetric dark matter model with a dark photon portal

open access: yesJournal of High Energy Physics, 2019
Composite asymmetric dark matter scenarios naturally explain why the dark matter mass density is comparable with the visible matter mass density. Such scenarios generically require some entropy transfer mechanism below the composite scale; otherwise ...

Magnetogenesis from a rotating scalar: à la scalar chiral magnetic effect

open access: yesJournal of High Energy Physics, 2020
The chiral magnetic effect (CME) is a phenomenon in which an electric current is induced parallel to an external magnetic field in the presence of chiral asymmetry in a fermionic system.

Physics Beyond the Standard Model

open access: yes, 2009
I present a brief overview of some exciting possibilities for physics Beyond the Standard Model. I include short discussions of neutrino physics, the strong CP problem and axions, GUTs, large and warped extra dimensions, Little Higgs models and ...

b Physics Beyond the Standard Model [PDF]

open access: yes, 2002
I review the signals for New Physics in CP-violating measurements in B and Lambda_b decays. I also discuss ways of identifying this New Physics, should such a signal be found.Comment: 10 pages, LaTeX, 1 figure, ps file included.

Families from supergroups and predictions for leptonic CP violation

open access: yesJournal of High Energy Physics, 2017
As was shown in 1984 by Caneschi, Farrar, and Schwimmer, decomposing representations of the supergroup SU(M |N ), can give interesting anomaly-free sets of fermion representations of SU(M ) × SU(N ) × U(1).

Time-delayed electrons from neutral currents at the LHC

open access: yesJournal of High Energy Physics, 2021
We investigate long-lived particles (LLPs) produced in pair from neutral currents and decaying into a displaced electron plus two jets at the LHC, utilizing the proposed minimum ionizing particle timing detector at CMS. We study two benchmark models: the
