Pressure Distribution Inside Nucleons in a Tsallis-MIT Bag Model [PDF]
EntropyWe present a phenomenological framework based on the MIT bag model to estimate the pressure experienced by quarks and gluons inside nucleons. This is accomplished by implementing non-extensive Tsallis statistics for the two-component system.

Light-Front Field Theory on Current Quantum Computers
Entropy, 2021 We present a quantum algorithm for simulation of quantum field theory in the light-front formulation and demonstrate how existing quantum devices can be used to study the structure of bound states in relativistic nuclear physics.

Experimental Determination of the QCD Effective Charge αg1(Q)
Particles, 2022 The QCD effective charge αg1(Q) is an observable that characterizes the magnitude of the strong interaction. At high momentum Q, it coincides with the QCD running coupling αs(Q).

Analysis of Overlapping Resonances with Unitary Breit–Wigner and K-Matrix Approaches
Particles, 2022 We compare two methods for obtaining the parameters of overlapping resonances. The convenience of the Breit–Wigner (BW) approach is based on the fact that it operates with the masses and widths of the states.

QCD confronts heavy-flavor and exotic hadrons [PDF]
EPJ Web of Conferences, 2022 A review of QCD-based theory approaches to study the heavy-flavor and exotic hadrons is given. The focus is on the results from lattice QCD and from lattice QCD complemented by effective field theories.

Physics Letters B, 2022 Structure functions of polarized spin-1 hadrons will be measured at various accelerator facilities in the near future. Recently, transverse-momentum-dependent and collinear parton distribution functions were theoretically proposed at twist 3 and twist 4 ...

Investigating the origin of strangeness enhancement in small systems through multi-differential analyses [PDF]
EPJ Web of Conferences, 2022 The main goal of the ALICE experiment is to study the physics of strongly interacting matter, including the properties of the quark-gluon plasma (QGP). The relative production of strange hadrons with respect to non-strange hadrons in heavy-ion collisions

The multiple-charm hierarchy in the statistical hadronization model
Journal of High Energy Physics, 2021 In relativistic nuclear collisions the production of hadrons with light (u,d,s) quarks is quantitatively described in the framework of the Statistical Hadronization Model (SHM). Charm quarks are dominantly produced in initial hard collisions but interact

Four-quark matter—a new era of spectroscopy
AAPPS Bulletin, 2021 In 1964, both Gell-Mann and Zweig proposed the famous Quark Model in particle physics, which tells us hadrons are built of three quarks (baryons) or quark anti-quark pair (mesons).

First Results of Studying EAS Cores Using a High-Mountain Ionization Calorimeter
Particles, 2023 In high-altitude experiments to study the central cores of EAS at E0 ≳ 1016 eV (√s ≳ 5 TeV) using X-ray emulsion chambers and ionization calorimeters, phenomena such as the coplanarity of the arrival of the most energetic particles in super families of γ-
