79. From Coulomb breakup of halo nuclei to neutron radiative capture

Prof. Pierre Capel (Univ. Bruxelles)

Nuclear Structure and Astrophysics

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...

31. Proton-proton and Lambda-proton correlations measured in p+Nb collisions at 3.5 GeV with HADES

Mr Oliver Arnold (Technische Universitaet Muenchen)

Hadron Physics

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...

63. From hypernuclei to neutron stars: looking for the pieces of the puzzle

Dr Diego Lonardoni (MSU)

Nuclear Structure and Astrophysics

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...

72. DEPFET for BELLEII

Dima Levit (tum)

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...

40. Measurements of heavy flavours with the ALICE experiment at the LHC

Mrs Denise Godoy (ss)

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....

81. Exotic quarkonium states in CMS

Mr Leonardo Cristella (CERN)

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...
