We explore supersymmetric contributions to the decay K 0 S →μ + μ − , in light of current experimental data. The Standard Model (SM) predicts B(K 0 S →μ + μ − )≈5×10 −12 . We find that contributions arising from flavour violating Higgs penguins can enhance the branching fraction up to ≈35×10 −12 within different scenarios of the Minimal Supersymmetric Standard Model (MSSM), as well as...
The neutral pion is the lightest strongly interacting particle in Nature. Therefore, the properties of π0 decay are especially sensitive to the underlying fundamental symmetries of quantum chromodynamics (QCD). In particular, the π0 →γγ decay width is primarily defined by the spontaneous chiral symmetry breaking effect (chiral anomaly) in QCD. Theoretical activities in this domain over the...
We discuss the importance of the electroweak (``Cho-Maison")
monopole and emphasize that the detection of this monopole,
not the Higgs particle, should be the final and topological test
of the standard model. If discovered, it should become the first
magnetically charged stable topological elementary particle in
the history of physics. Moreover, it has deep cosmological implications.
It...

Searches for permanent electric dipole moments (EDMs) of fundamental particles, atoms and molecules are promising experiments to constrain and potentially reveal beyond Standard Model (SM) physics. A non-zero EDM is a direct manifestation of time-reversal (T) violation, and, equivalently, violation of the combined operation of charge-conjugation (C) and parity inversion (P). Identifying new...
The anomalous magnetic moment of the muon can be both measured and computed to a very high precision, making it a powerful probe to test the standard model and search for new physics. The previous measurement by the Brookhaven E821 experiment found about three standard deviation discrepancy from the predicted value. The Muon g-2 experiment at Fermilab will improve the precision to 140 parts...
The search for magnetic monopoles is a fascinating interdisciplinary field with implications in particle physics, astrophysics, and cosmology.
In this talk, the status of the searches for magnetic monopoles at accelerators and in the penetrating cosmic radiation is reviewed with emphasis on the most recent results from the MoEDAL experiment at the LHC.
A comprehensive set of resonances measured by the ALICE experiment in pp, p-Pb and Pb-Pb collisions at different LHC energies, will be presented. In particular, the production of hadronic resonances such as $\rho^{0}$(770), K*(892), $\phi$(1020), $\Sigma$(1385)$^{\pm}$, $\Lambda$(1520) and $\Xi$(1530)$^{0}$ will be discussed in detail. In heavy-ion collisions the hadronic resonances are...
I present theoretical calculations for Higgs-boson and top-quark production,
including high-order soft-gluon corrections. I discuss charged-Higgs production in association with a top quark or a W boson, as well as single-top and top-antitop production. Total cross sections as well as transverse-momentum and rapidity distributions of the top quark or the Higgs boson are presented for various...
A new data analysis was performed, based on looser selection criteria and multivariate approach. Oscillation parameters and nu_tau cross-section have been determined with a reduced statistical uncertainty, and the discovery of tau neutrino appearance is confirmed with an improved significance level. Moreover, the search for electron neutrino events has been extended to the full dataset,...
The Very Special Relativity Electroweak Standard Model (VSR EW SM) is a theory with
SU(2)_L×U(1)_R symmetry, with the same number of leptons and gauge fields as in the usual Weinberg-Salam (WS) model.
No new particles are introduced. The model is renormalizable and unitarity is preserved. However,
photons obtain mass and the massive bosons obtain different masses for different...
