Oral Presentation
The search for a spin-0 or spin-2 state decaying into two photons in a large mass range is presented, using about 10 fb-1 of p-p collisions at 13 TeV.

Higgs Physics
Oral Presentation
A search for new physics in high-mass diphoton events is presented. The analysis is performed by looking for bumps on the continuum diphoton mass spectrum. This clean signature is sensitive to high-mass gravitons predicted by models with extra dimensions and to scalar resonances arising from many extensions of the standard model. The talk focuses on the recent results obtained using data...

Beyond the Standard Model
Oral Presentation
The recently-proposed relaxion framework aims to provide a novel dynamical solution to the Standard Model hierarchy problem. We examine the phenomenology of a new TeV-scale QCD-like sector associated with particular relaxion models in which non-perturbative effects in the new sector provide the stopping-potential for the relaxion. Among the host of potential new-physics signals, whose impact...

Beyond the Standard Model
Oral Presentation
We consider a dark sector with SU(3)C×U(1)Y×U(1)X and three families of dark fermions that are chiral under dark U(1)X gauge symmetry, whereas scalar dark matter X is the SM singlet. U(1)X dark symmetry is spontaneously broken by nonzero VEV of dark Higgs field ⟨Φ⟩, generating the masses of dark fermions and dark photon Z′. The resulting dark Higgs boson ϕ can be produced at the LHC by dark...

Beyond the Standard Model
Oral Presentation
We propose an NMSSM scenario that can explain the excess in the diphoton spectrum at 750 GeV recently observed by ATLAS and CMS. We show that in a certain limit with a very light pseudoscalar one can reproduce the experimental results without invoking exotic matter. The 750 GeV excess is produced by two resonant heavy Higgs bosons that subsequently decay to light pseudoscalars. Each of these...

Beyond the Standard Model
Oral Presentation
A slight excess has been observed in the first data of photon-photon events at the 13~TeV LHC, that might be interpreted has a hint of physics beyond the Standard Model.
We show that a completely model-independent measurement of the photon-photon coupling of a putative 750 GeV resonance will be possible using the forward proton detectors scheduled at ATLAS and CMS.
We consider the...

Beyond the Standard Model
Oral Presentation
Inspired by the 750 GeV resonance displayed in Run II by the ATLAS and CMS experiments, we propose to incorporate it in an extension of the MSSM based on a suitable gauge symmetry G. The combination of G and a U(1) R-symmetry yields a unique renormalizable superpotential containing a G-singlet superfield S, such that G breaks to MSSM at scale M with supersymmetry unbroken. The mass of the...

Oral Presentation
We present a possible interpretation of the excess in the di-photon channel
at 750 GeV recently observed by ATLAS and CMS as the radion of the five-dimensional
Randall-Sundrum model. We show that the Higgs-radion scenario can give a cross section
of (5--15) fb in the di-photon final state at 750 GeV while at the same time giving a very SM-like state at 125 GeV. Tests of the model using other...
