We calculate, for the first time, the NNLO QCD corrections to identified heavy hadron production at hadron colliders. The calculation is based on a flexible numeric framework which allows the calculation of any distribution of a single identified hea

Neutrino-neutrino refraction dominates the flavor evolution in core-collapse supernovae, neutron-star mergers, and the early universe. Ordinary neutrino flavor conversion develops on timescales determined by the vacuum oscillation frequency. However,

Longitudinal polarisation of the weak bosons is a direct consequence of Electroweak symmetry breaking mechanism providing an insight into its nature, and is instrumental in searches for physics beyond the Standard Model. We perform a polarisation stu

In this talk, after a short overview of the history of the discovery of tetra-quarks and penta-quarks, we will discuss a possible interpretation of such states in the framework of a 40-years-old "string junction" picture that allows a unified QCD des

Semileptonic decays of vector mesons $$\rho $$ , $$\omega $$ , ϕ into a pion and lepton pair $${{e}^{ + }}{{e}^{ - }},{{\mu }^{ + }}{{\mu }^{ - }}$$ are described in the chiral Nambu–Jona–Lasinio (NJL) model. Mixing of $$\omega $$ with ϕ is tak

Investigation of properties of nuclear matter at extremely high temperature and/or extremely high baryon densities under laboratory conditions is one of the fundamental lines of research in high-energy physics. Throughout the past decades, such inves

We propose a renormalizable Standard Model extension based on $$\Delta(54)$$ symmetry which successfully accommodates the recent experimental values of the physical observables of the quark sector, including six quark masses, three quark mixing angle

We compute the dilepton production rate from deconfined phase of quark-gluon plasma using the quasi-particle model (QPM). The computation is based on an extension of our previous work. In this model, the finite quark mass is replaced by the effective

New upper limits on the intrinsic-charm contribution to the proton are obtained on the basis of experimental data on the existence of pentaquarks involving a hidden charm. Possible distributions of heavy quarks within the proton are analyzed.

The concept of coherence in the scattering of neutrinos and antineutrinos off nuclei is discussed. Motivated by the results of the COHERENT experiment, a new approach to coherence in these processes is proposed, which allows a unified description of
