I shall report on different reactions where hidden charm states, of molecular type or other, can be seen. In particular I will describe theoretically the $\Lambda_b \to J/\psi K^- p $ and $\Lambda_b \to J/\psi \pi^- p $ reactions, where experimentally some peaks have been observed and associated to two pentaquark states by the LHCb collaboration. Then I will present studies of related...

An isobar model for photoproduction of kaons on the proton was recently constructed [1]
utilizing new experimental data from CLAS, LEPS and GRAAL collaborations. Higher-spin
nucleon (3/2 and 5/2) and hyperon (3/2) resonances were included using the consistent
formalism by Pascalutsa and found to play an important role in data description.
The set of chosen nucleon resonances agrees...

We study light baryons using a simple relativistic but non covariant Coulomb Gauge QCD inspired model. A variational basis is employed to compute the energies and wavefunctions of the baryon states, for different values of angular momentum and parity. Results are obtained for both the Nucleon and the Delta sectors. A special look is given to the high angular momentum states going up to J =...

Weak scale supersymmetry is one of the best motivated and studied extensions of the Standard Model and it is explored, together with other new physics scenarios, exploiting the recent increase in the center of mass energy of the proton-proton collisions at the Large Hadron Collider. This talk summarizes the searches performed with the ATLAS detector in the first run-2 data using 3.2 fb^(-1) at 13 TeV.

The ATLAS collaboration has searched for the Standard Model Higgs Boson
in the first run-2 data using 3.2 fb^(-1) at 13 TeV. Results are
presented in terms of central value and limits on the fiducial and total
cross-sections.
Several "Beyond Standard Model" theories predict the existence of
additional heavy Higgs particles or di-Higgs resonances. Searches are
conducted using the...

We calculate cross sections for diphoton production
in (semi)exclusive $PbPb$ collisions, relevant for the LHC.
The calculation is based on equivalent photon approximation in
the impact parameter space.
The cross sections for elementary $\gamma \gamma \to \gamma \gamma$
subprocess are calculated including two different mechanisms.
We take into account box diagrams
with leptons and...

Rare weak decays of heavy mesons, nowadays experimentally measured, allow for sensitive testing of the validity of the Standard Model. To achieve a reliable theoretical predictions, one needs, besides an appropriate description of the weak transition, to properly describe the hadronic effects. The covariant quark model with infrared confinement represents a suitable framework for such purpose....
