We report on the search for visible decays of exotic mediators from data taken in "beam-dump" mode with the NA62 experiment. The NA62 experiment can be run as a "beam-dump experiment" by removing the Kaon production target and moving the upstream collimators into a "closed" position.

We will present preliminary COMPASS results on the Deeply Virtual Compton Scattering (DVCS) cross section, which was obtained from exclusive single-photon production by scattering the 160 GeV muon beams of the SPS M2 beamline off a 2.5 m long liquid hydrogen target. The recoil proton was measured by a barrel-shaped time-of-flight detector surrounding the target. The scattered muons were...

The Jiangmen Underground Neutrino Observatory (JUNO) is a medium-baseline reactor neutrino experiment currently under construction in southern China. $20\,\mathrm{kton}$ LAB-based liquid scintillator target is contained inside the Central Detector, a $35.4\,\mathrm{m}$ diameter spherical acrylic vessel. The scintillator light emitted from the Central Detector will be read out by the...

Results of the ATLAS experiment on the exotic hadrons are presented. Studies of pentaquark and tetraquark states in B-hadron decays and recent results on the signals of resonant $J/\psi$-pair production are reviewed. Perspectives for future and ongoing analyses of exotic states are highlighted.

The low-energy QCD, the theory within the Standard Model describing the strong interaction, is still missing fundamental experimental results in order to achieve a breakthrough in its understanding. Among these experimental results, the low-energy kaon-nucleon/nuclei interaction studies are playing a key-role, with important consequences going from particle and nuclear physics to astrophysics...

the decay of the SM Higgs boson and their subsequent decay into standard model particles. We compute the projected sensitivity, both model-independently and with a minimal model, of using the muon spectrometer of the CMS detector at the HL-LHC experiment for ggF, VBF, and Vh production modes of the Higgs boson and various... -

The Super-Kamiokande (SK) experiment is a 50 kton water Cherenkov detector located in the Kamioka Observatory in Japan and in operation since 1996, observing neutrinos and anti-neutrinos from many different sources. In 2020, SK moved to the SK-Gd phase, in which gadolinium sulfate octahydrate was added to the water in the detector to improve the detection efficiency of neutrons. Such neutrons...

The search for new physics such as supersymmetry (SUSY) and other beyond-the-standard-model physics is a major goal of the LHC physics program. The talk will cover the most recent results of SUSY searches using 137 fb$^{-1}$ data collected in 2016-2018 with the CMS detector at the LHC.

We study one of the important signature of quark gluon plasma (QGP) that is electromagnetic probes. The electromagnetic probes as diphotons are considered as a best signals for the formation and evolution of QGP.
