Workshop for young scientists with research interests focused on physics at FAIR

Simulations of dense quark matter are hampered by the sign problem, invalidating the usual importance sampling based methods of lattice QCD, and preventing the determination of the location of the critical point on the QCD phase diagram. Possible workarounds and solutions to the problem are discussed, with emphasis on the review of the recent successes of the Complex Langevin approach, based...

The advent of new accelerators technologies, like the use of intense and stored antiprotons beams, will set an inflection point in what we know today as Modern Physics. In particular, the PANDA experiment at the FAIR facility in Darmstadt, (Germany), will help to elucidate many of the still obscure aspects of the strong interaction, and consequently build a link between nuclear and hadron...

Pseudoscalar mesons (P) decaying into lepton-antilepton pairs can provide a signal to physics beyond the Standard Model. Within the Standard Model P->l+l- proceeds via a two-photon intermediate state. Therefore it is a fourth order electromagnetic process, and thus suppressed. Determinations of upper limits has previously been performed for pi0, eta and eta' decaying to lepton-antilepton...

Charmonium spectroscopy is an ideal tool to systematically study the strong interaction between the fundamental building blocks of matter, quarks and gluons. From a theoretical and experimental point of view, charmonium is considered as one of the most controllable two-quark systems. Hence, precision measurements of the properties of charmonia allow a thorough study of the non-perturbative...

The Compressed Baryonic Matter project (CBM) at the upcoming SIS100 heavy-ion accelerator at the FAIR (Darmstadt, Germany) will explore the QCD phase diagram in so far unknown regions of moderate temperatures and high baryonic densities for the hadronic freeze-out. Thus, the experiment is expected to gain progress in the understanding of the phase transition between hadronic matter and a...

We study the broad light scalar kaonic resonance k0*(800) as a dynamically generated state. Namely, we show that this resonance emerges when investigating the heavier quark-antiquark scalar state k0*(1430) dressed by quantum fluctuations with one kaon and one pion circulating in the loops. We analyse the spectral function in the whole kaonic sector up to 1.8 GeV and determine the position of...
