Short Contribution
Coulomb breakup has been proposed as an indirect method to deduce the cross section of radiative captures of astrophysical interest [1]. In Coulomb breakup, the projectile dissociates into lighter fragments through its interaction with a heavy (high Z) target. Assuming the dissociation to be due to the sole Coulomb interaction, the reaction can be described as an exchange of virtual photons...

Short Contribution
In the last years, the hyperon-nucleon interaction became the focus of attention by an astrophysical measurement of a quite heavy neutron star of two solar masses. Model calculations, which try to describe such a heavy star usually fail, because of the appearance of hyperons in the model predictions which lead to a too strong softening of the equation of state. Because the models need input...

Short Contribution
The onset of hyperons in the core of neutron stars and the consequent softening of the equation of state have been questioned for a long time. We tackle the problem within a quantum Monte Carlo computational scheme. We first show that a repulsive three-body hyperon-nucleon force is needed to correctly describe the systematics of Λ-hypernuclei [1,2,3]. Then, we employ the same potential to...

Applications and Instrumentations
Short Contribution
The Belle II experiment is a B-factory which is being built at the asymmetric electron-positron collider SuperKEKB in Japan.
The experiment aims at measuring the differences between matter and anti-matter in the B and D meson decays.
The 2-layer active pixel detector based on the novel DEPFET technology is an innermost detector in the experiment and a part of the vertex detector.
The pixel...

Relativistic Heavy Ion Physics
Poster
Fluctuations of various observables in heavy-ion collisions at ultra-relativistic energies have been extensively studied as they provide important signals regarding the formation of Quark Gluon Plasma. Because of the large number of produced particles in each event, a detailed study of event-by-event multiplicity fluctuations has been proposed as one of the signatures of the phase transition....

Relativistic Heavy Ion Physics
Short Contribution
Using large data samples of di-muon events, CMS has performed detailed
measurements and searches for new states in the field of exotic quarkonium. We
present our results on the production of prompt and non-prompt X(3872),
detected in the J/ψ ππ decay channel, which extend to higher pT values than in
any previous measurement. The cross-section ratio with respect to the ψ(2S) is
given...
