We show that a very clear signal of the presence of a strong magnetic field during the early stage of a high-energy heavy-ion collision is provided by the decay of the $Z^0$ into dimuon pairs. We find that the process is highly anisotropic, producing pairs mainly out of plane, as signaled by a negative value of $v_2$, and leads to an antimuon transverse momentum distribution which peaks at a...

Top quark pair production in association with a Z boson (ttZ) is a rare process within the Standard Model (SM) that provides a stringent test of SM predictions and sensitivity to potential new physics.

The measurement of the gluon-jet fraction in a jet sample relies on various jet parameters and is inherently model dependent. Jet properties are defined within a hadronization model embedded in the Monte Carlo generator.

We developed a new spectral function approach for calculation of parton distribution in hadrons for the valence quark region. The approach explicitly introduces the light-front wave function of the residual state allowing to construct the light-front spectral function of the hadron in which case valence quarks are massless embedded in the mean field of the residual state.

The search for gravity arising from large extra dimensions at collider energies is explored in the transplanckian regime, where the center-of-mass energy, $\sqrt{s}$, is much greater than both exchanged momentum, $Q$, and the extra dimension Planck mass scale $M_D$. The primary signature of large extra dimension gravity in the transplanckian regime is the production of high-mass dijet events...

Recent LHC results of proton-lead collisions with large forward rapidity gaps show a dominant role of photon exchange over pomeron one.

A unified framework for describing the production of both baryons and exotic multiquark states at large transverse momentum is presented.

We show that this model successfully accounts for the observed strong scaling violation in inclusive proton production across a wide energy range,...

Glueballs are predicted to be abundantly produced in glue-rich processes, such as charmonia decays....
