Particle Physics: Experiment and Phenomenology: neutrino,dark matter searches, heavy quarks
Flux-integrated semiexclusive differential cross sections for charged-current quasielastic and neutral-current elastic neutrino scattering on argon are analyzed. The cross sections are calculated using the relativistic distorted-wave impulse approximation and compared with recent MicroBooNE data. It was found that the measured cross sections can be described well within the experimental...
An axion is a hypothetical particle being a quant of pseudoscalar field. It has been originally postulated by Peccei and Quinn in 1977 to resolve the strong CP problem in QCD. If axions exist, they are of interest as a possible component of cold dark matter. The axion–photon coupling distorts the electromagnetic field and leads to the inverse Primakoff effect which can be observed with...
Data from the Large Hadron Collider lead to strong constraints on the parameter space of low-energy supersymmetry. In particular, these data practically exclude supersymmetric dark matter (DM) in the traditional cosmology. We argue that in $R^2$-modified gravity superheavy particles with the interaction strength typical for supersymmetry can be realistic candidates for the role of the carriers...
The SPD NICA is planned to operate as a universal facility for comprehensive study of the unpolarized and polarized gluon content of the nucleon at large Bjorken-x, using different hard probes. The first one is charmonium
production processes. The experiment aims to provide access to the gluon helicity, gluon Sivers and Boer-Mulders PDFs in the nucleon. In this talk, we present an overview of...
The current state of top quark physics is considered. The main
experimental results obtained at the Large Hadron Collider (LHC) are summarized.
