Relativistic nucleus–nucleus collisions offer a unique possibility for studying nuclear matter under the influence of high temperature and pressure. During the collision a system of interacting nucleons, resonances, and mesons, called hadronic fireball, is created.\par
The Dielectron Spectrometer HADES operated at the SIS18 synchrotron of FAIR/GSI Darmstadt recently provided new intriguing...

38. Spectator induced electromagnetic effects on charged meson production in nucleus-nucleus collisions from NA61/SHINE at CERN SPS

Sneha Bhosale (Institute of Nuclear Physics PAS)

Parallel

The SPS Heavy Ion and Neutrino Experiment (NA61/SHINE) studies the properties of hadron production in collisions of beam hadrons and nuclei with fixed hadronic and nuclear targets.
In this talk I will discuss the space-time evolution of the system of strongly interacting matter created in the collision, studied from the modification of charged pion spectra and $\pi^{+}/\pi^{-}$ ratios by the...

28. Beauty production in pp and Pb–Pb collisions with ALICE

Himanshu Sharma (Institute of Nuclear Physics PAS)

Parallel

Nuclear collisions provide an excellent opportunity to understand the properties of a strongly coupled deconfined medium $i.e.$ the quark-gluon plasma (QGP), along with the production mechanism of heavy quarks (beauty or charm quarks). Beauty quarks are produced by hard parton scatterings in hadronic collisions and their production can be measured by the decay products of the B meson. In pp...

44. Decay processes of ϕ ( 2170 ) to kaonic resonances

Alberto Martinez Torres (University of São Paulo)

Parallel

We have recently studied the strong decays of φ(2170) to final states involving the kaonic resonances K(1460), K1(1270) and K1(1400), on which experimental data have been extracted by the BESIII Collaboration. The formalism developed is based on interpreting φ(2170) and K(1460) as states arising from three-hadron dynamics. For K1(1270) and K1(1400) we investigate different descriptions, such...
