The aim of this review is to demonstrate that there exists a coherent picture of strong
interactions, based on instantons. Starting from the first principles of Quantum …

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 recently reported excess in the diphoton resonance search by ATLAS
and CMS. We investigate the available parameter space in the combined run-1 and run-2 …

We consider the possibility of an enlarged QCD color group, SU (3+ N′) spontaneously
broken to SU (3) c× SU (N′) with extra vectorlike quarks transforming in the fundamental …

A bstract We propose a simplified model of dark matter with a scalar mediator to
accommodate the di-photon excess recently observed by the ATLAS and CMS …

We consider the phenomenology of a resonance that couples to photons but not gluons, and
estimate its production rate at the LHC from photon-photon fusion in elastic pp scattering …

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 We present a possible interpretation of the recent diphoton excess reported by the
early\(\sqrt {s}= 13\) TeV LHC data in quark seesaw left-right models with vectorlike fermions …

A bstract We discuss the implications of the significant excesses in the diphoton final state
observed by the LHC experiments ATLAS and CMS around a diphoton invariant mass of …

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 …
