Twist analysis of the spin-orbit correlation in QCD

open access: yesJournal of High Energy Physics
We present a QCD analysis of the twist-three parton distribution functions associated with the spin-orbit correlation of quarks and gluons in spin- 1 2 $$ \frac{1}{2} $$ and spin-0 hadrons. We derive exact non-perturbative identities decomposing the spin-

Exploring the magnetic dipole moments of T QQ q ¯ s ¯ $$ {T}_{QQ\overline{q}\overline{s}} $$ and T QQ s ¯ s ¯ $$ {T}_{QQ\overline{s}\overline{s}} $$ states in the framework of QCD light-cone sum rules

open access: yesJournal of High Energy Physics, 2023
Motivated by the recent observation of the tetraquark T cc + $$ {T}_{cc}^{+} $$ , we investigate the magnetic dipole moments of the possible single and double strange partners, T QQ q ¯ s ¯ $$ {T}_{QQ\overline{q}\overline{s}} $$ and T QQ s ¯ s ¯ $$ {T}_ ...

Study of the electromagnetic form factors of the nucleons in the timelike region

open access: yesJournal of High Energy Physics
The electromagnetic form factors G E and G M of the proton and neutron in the timelike region are extracted in a study of the processes e + e − → p ¯ p $$ \overline{p}p $$ and e + e − → n ¯ n $$ \overline{n}n $$ .

Hades experiments: investigation of hadron in-medium properties

open access: yesJournal of Physics: Conference Series, 2013
Hadron modifications in nuclear matter are discussed in connection to chiral symmetry restoration and/or hadronic many body effects. Experiments with photon, proton and heavy ion beams are used to probe properties of hadrons embedded in nuclear matter at different temperatures and densities.

Hadron Properties with FLIC Fermions [PDF]

open access: yes, 2008
The Fat-Link Irrelevant Clover (FLIC) fermion action provides a new form of nonperturbative O(a)-improvement in lattice fermion actions offering near continuum results at finite lattice spacing. It provides computationally inexpensive access to the light quark mass regime of QCD where chiral nonanalytic behaviour associated with Goldstone bosons is ...

Hadron Properties in the Vicinity of $T_c$

open access: yes, 1994
Modifications of hadron masses and some of their basic properties with temperature or nuclear density are considered as one possible signature for the formation of dense hadronic matter in nuclear collisions. We discuss here some basic results on the temperature dependence of hadron properties obtained from calculations of hadron correlation functions,

T-even TMDs for the spin-0 pseudo-scalar mesons upto twist-4 using light-front formalism

open access: yesJournal of High Energy Physics
We have investigated the pseudo-scalar meson structure in the form of transverse momentum-dependent parton distribution functions (TMDs) in the light-front based holographic model and quark model.

Heavy flavour spectroscopy and hadron properties from LHCb

open access: yesEPJ Web of Conferences, 2018
The LHCb experiment is designed to study the properties and decays of heavy flavored hadrons produced in pp collisions at the LHC. The data collected enables precision spectroscopy studies of beauty and charm hadrons.

Improving on the PYTHIA modelling of equal-scale multi-parton distribution functions

open access: yesJournal of High Energy Physics
Multi-parton distribution functions (mPDFs) are non-perturbative objects that are important in the prediction of multiple scattering rates at hadron colliders. In the case where the scales associated with all partons in the mPDF are the same, we have two
