We identify the two scalar leptoquarks capable of generating sign-dependent contributions to leptonic magnetic moments, 𝑅2∼(3,2,7/6) and 𝑆1∼(3,1,−1/3), as is a strong possibility given current measurements. We consider the case in which the electron and muon sectors are decoupled, and real-valued Yukawa couplings are specified using an up-type quark mass-diagonal basis. This allows us to...
The M1 radiative transitions of heavy flavor baryons are studied in the framework of Effective Mass Scheme (EMS) within the quark model. The intent of the EMS lies in the fact that the masses of the quarks inside the baryon are modified as a consequence of one-gluon exchange interaction with the spectator quarks and it treats all the quarks at the same footing. The baryon mass can be written...
Run 2 of the LHC has witnessed the observation of rare top quark production processes predicted by the Standard Model and has enabled searches for heavily suppressed flavour-changing-neutral-current interactions of the top quark. In this contribution the highlights are shown of searches by the ATLAS experiment for rare processes involving top quark. The associated top quark production...
Run 2 of the Large Hadron Collider, with 140/fb of proton proton collisions at a center-of-mass energy of 13 TeV, has produced over 10^8 top quarks. The large sample has enabled precise measurements of the production cross section in the "classical" top quark production processes, as well as new measurements in previously unobserved kinematic regimes and production processes. In this...
The vector bosons decaying into two same leptonic flavor and heavy-flavor jets have been studied using proton-proton collisions at the Large Hadron Collider with the CMS experiment. This study is important to test pQCD theory by comparing experimental cross section with theoretical predictions and to distinguish signal from the background in many SM processes and BSM searches. The kinematic...
The ATLAS experiment has performed measurements of B-meson rare decays proceeding via suppressed electroweak flavour changing neutral currents, and of mixing and CP violation in the neutral B meson systems.
This talk will focus on the latest results from the ATLAS collaboration, such as rare processes B^0_s → mu mu and B^0 → mu mu, and CP violation in the B_s^0 —> J/psi phi decays. In the...
