We investigate photo-production of vector mesons J/Psi and Upsilon measured both at HERA and LHC, using 2 particular fits of inclusive unintegrated gluon distributions. The fits are based on non-linear Balitsky-Kovchegov evolution (Kutak-Sapeta gluon; KS) and next-to-leading order Balitsky-Fadin-Kuraev-Lipatov evolution (Hentschinski-Sabio Vera-Salas gluon; HSS). We find that linear...
The study of photon-induced reactions in collisions of heavy nuclei at RHIC and the LHC has become an important direction of the research program of these facilities in recent years. In particular, the production of vector mesons in ultra-peripheral collisions (UPC) has been intensively studied. Owing to the intense photon fluxes, the two nuclei participating in such processes undergo...
ALICE is one of the four main experiments at the CERN Large Hadron Collider. The location of the ALICE detector allows us to study the muonic component of cosmic rays, since it is located 52 meters underground with 28 meters of rock above it. The ALICE detector is able to detect atmospheric muons from extensive air showers, making possible the study of topics related to cosmic-ray physics. At...
Currently, the DUNE Collaboration is making several tests in small detectors with the components that will be used in the DUNE detectors to avoid and detect future problems in the massive detectors. In this talk, I show the design and simulation of the cryostat and HV system for a LArTPC to make tests of relevance in cool electronics and photodetection for the DUNE Collaboration.
The design...
The high energy peaked blazars are known to undergo episodes of flaring in GeV-TeV gamma-rays involving different time scales and the flaring mechanism is not yet well understood despite long term simultaneous multiwavelength observations. These gamma-rays en route to Earth undergo attenuation by the extra galactic background light.
Using the photohadronic model, where the seed photons of...
The spin program at the STAR experiment at the Relativistic Heavy Ion Collider (RHIC) has explored many interesting topics and has helped our understanding of nuclear physics. In particular, non-vanishing transverse single-spin asymmetry measurements at RHIC and other experiments have shown that there is a rich substructure of the nucleon that needs further exploration in both theory and...
Here, in the axioms of dynamic space-matter, a unified theory of all mathematical and physical theories is presented, with the possibility of studying the energy levels of the singularity of the set of Rji (n) objects of singularity in the quantum system of OLji (m) coordinates, the dynamic space-matter of the whole Universe.

An overview of the status of the ATLAS Forward Detector system consisting on the detectors: LUCIC, ZDC, AFP and AlFA, will be given. I will also report on planned upgrades to each detector for LHC RUN-3 and HL-LHC.
AN overview of the MoEDAl experiment will be given, including latest results. In addition MoEDAL's plans for LHC Run-3 and Run-4 data taking will be presented, emphasizing the MAPP (MoEDAL Apparatus for Penetrating Particles) upgrade and its physics program.

Vector mesons are copiously produced in ultra-peripheral collisions where the impact parameter is larger than the sum of the radii of the two projectiles, implying that electromagnetic induced processes become dominant.
Light vector meson photoproduction cross sections can be used to study Glauber-Gribov shadowing effects at the hadronic level while the photoproduction of heavy vector...
