A bstract Heavy scalar and pseudoscalar resonance searches through the\(gg\to S\to
t\overline {t}\) process are challenging due to the peculiar behavior of the large interference …

A bstract We study the conditions for a new scalar resonance to be observed first in
diphotons at the LHC Run-2. We focus on scenarios where the scalar arises either from an …

A bstract Motivated by the tantalizing excesses recently reported in the di-photon invariant
mass spectrum at the LHC, we scrutinize some implications of scalar di-photon resonances …

We explain the recent diphoton excesses around 750 GeV by both ATLAS and CMS as a
singlet scalar Φ which couples to SM gluon and neutral gauge bosons only through higher …

A slight excess has been observed in the first data of photon-photon events at the 13 TeV
Large Hadron Collider that might be interpreted as a hint of physics beyond the standard …

More than 3 σ deviations from the standard model are observed in the angular observable P
5′ of B→ K* μ+ μ-and muon g-2. To resolve these anomalies, we extend the standard …

We explore several perturbative scenarios in which the diphoton excess at 750 GeV can
potentially be explained: a scalar singlet, a two Higgs doublet model (2HDM), a 2HDM with …

We argue that the diphoton excess recently reported by ATLAS and CMS can be explained,
along with several anomalies seen in the flavor sector, in models where a Standard Model …

A 750 GeV resonance has been observed at the run 2 LHC in the diphoton channel. In this
paper, we explain this resonance as a CP-even scalar S that triggers the spontaneous …

A bstract We interpret the recently observed excess in the diphoton invariant mass as a new
spin-0 resonant particle. On theoretical grounds, an interesting question is whether this new …
