Proton electromagnetic generalized polarizabilities
Frontiers in PhysicsElectromagnetic polarizabilities are fundamental properties of the proton that characterize its response to an external electromagnetic (EM) field. The generalization of the EM polarizabilities to non-zero four-momentum transfer opens up a powerful path ...

High energy QCD: multiplicity dependence of quarkonia production
European Physical Journal C: Particles and Fields, 2021 In this paper we propose an approach which demonstrates the dependence of quarkonia production on the multiplicity of the accompanying hadrons. Our approach is based on the three gluon fusion mechanism, without assuming the multiplicity dependence of the

Physics Letters B, 2017 We show that the experimental data of transverse momentum (pT) spectra of identified hadrons released recently by ALICE collaboration for p–Pb collisions at sNN=5.02 TeV exhibit a distinct universal behavior — the quark number scaling.

Hadron Freeze-Out and Qgp Hadronization [PDF]
, 1999 Abundances and $m_\bot$-spectra of strange and other hadronic particles emanating from central 158-200 A GeV reactions between nuclei are found to originate from a thermally equilibrated, deconfined source in chemical non-equilibrium. Physical freeze-out parameters and physical conditions (pressure, specific energy, entropy, and strangeness) are ...

Annual Review of Nuclear and Particle Science, 2009 We review the theory of hadronic atoms in the framework of quantum chromodynamics, with photons and electrons included (QCD+QED). We illustrate the method by means of π+π− atoms and briefly consider the application of the same approach to several other hadronic atoms.

Detector-size upper bounds on dark hadron lifetime from cosmology
Journal of High Energy Physics, 2019 We show that in a confining hidden valley model where the lightest hidden particles are dark hadrons that have mass splittings larger than O 0.1 $$ \mathcal{O}(0.1) $$ GeV, if the lightest dark hadron is either stable or decays into Standard Model (SM ...

Excited Hadron Channels in Hadronization
Proceedings of 11th International Conference on Hard and Elecctromagnetic Probes of High-Energy Nuclear Collisions — PoS(HardProbes2023)The proper treatment of hadronic resonances plays an important role for many aspects of heavy ion collisions. We expect this to be the case also for hadronization, due to the large degeneracies of excited states, and the abundant production of hadrons from their decays.

Circular attractors as heating mechanism in coherent electron cooling
Physical Review Accelerators and Beams, 2022 We show that under certain conditions a longitudinal mismatch between an electron and a hadron beam in a coherent electron cooling (CeC) scheme creates a circular attractor in the longitudinal phase space of the cooled hadrons.

Collisional Broadening within a Hadronic Transport Approach
Universe, 2023 We explore the emergence of the collisional broadening of hadrons under the influence of different media using the hadronic transport approach SMASH (Simulating Many Accelerated Strongly interacting Hadrons), which employs vacuum properties and contains ...
