The hints for a new resonance at 750 GeV from ATLAS and CMS have triggered a significant
amount of attention. Since the simplest extensions of the standard model cannot …

A bstract Heavy vector-like quarks coupled to a scalar S will induce a coupling of this scalar
to gluons and possibly (if electrically charged) photons. The decay of the heavy quark into …

A bstract Recent LHC data hinted at a 750 GeV mass resonance that decays into two
photons. A significant feature of this resonance is that its decays to any other Standard …

Motivated by a diphoton anomaly observed by ATLAS and CMS we develop an SFitter
analysis for a combined electroweak-Higgs sector, and a scalar portal at the LHC. The …

We consider the di-photon signal arises from two bunches of collimated photon jets emitting
from a pair of highly boosted scalars. Following the discussion of detecting the photon jets at …

This thesis explores the hierarchy problem of the Standard Model of particle physics, its
natural solutions, and the collider and cosmological signals of such theories. A review of the …
