Fast local thermalization of gluons and quarks characterizes the initial stages of relativistic heavy-ion collisions. For a theoretical description, effective weakly-coupled kinetic theories that rely on the quantum Boltzmann equation have been proposed and solved numerically. In the present work, I aim to account for the time evolution during the rapid equilibration of partons in a simplified...
The unitarity isobar model PionMAID is part of the Mainz MAID project with online
programs performing real-time calculations of observables, amplitudes
and partial waves (multipoles).
The model has been developed to analyze new high
precision data from A2 at MAMI, CBELSA/TAPS, GRAAL, and CLAS Collaborations
for pion photoproduction on protons and neutrons.
The background is described in...
In the journey to explore the strong interaction among hadrons, ALICE has for the first time flared out its femtoscopic studies to nuclei. The large data sample of high-multiplicity pp collisions
√s = 13 TeV allows the measurement of the proton-deuteron (p-d) momentum correlations.
The femtoscopic study of such systems opens the door to investigate the interaction in three-body systems as...
The hyperon puzzle, the observation that the two-solar-mass neutron stars existence is hardly explained by all models predicting the appearance of hyperons in the neutron star core is currently one of the unsolved key issues in the physics of compact stars. An experimental study of the reaction (e, e’K) on 208Pb 40 has been proposed by the Jefferson lab hypernuclear collaboration, and...
