121. Recent results from NA61/SHINE

Maja Katarzyna Mackowiak-Pawlowska (Warsaw University of Technology (PL))

NA61/SHINE at the CERN SPS is a fixed-target experiment pursuing a rich physics program including measurements for heavy ion, neutrino and cosmic ray physics. The main goal of the ion program is to study the properties of the onset of deconfinement and to search for the signatures of the critical point.

In this contribution the latest NA61/SHINE results on particle spectra as well as on...

162. Jets and charged hadrons in heavy ion collisions with the ATLAS detector

Helena Santos (LIP - Lisbon)

Ultrarelativistic heavy ion collisions at the LHC produce the Quark Gluon Plasma. Jets are a useful probe to study this state of matter as they are produced at the early stages of the collisions and are expected to be modified as propagating through the medium. One observable is the energy loss lowering the jet yields at a given transverse momentum. Other observables are the modification of...

133. QCD phase diagram and magnetic fields

Márcio Ferreira (CFisUC)

We examine possible effects of an external magnetic field on the phase diagram structure of QCD. The study is performed using NJL-type models. We focus on the influence of a magnetic field on the chiral and deconfinement phase transitions. Possible consequences of the Inverse Magnetic Catalysis effect on the QCD phase diagram at both finite chemical potential and temperature is analyzed. We...

160. Hollowness in pp at the LHC

Wojciech Broniowski (IFJ PAN)

Parameterizations of the pp scattering data at the LHC collision
energies indicate a hollow in the inelasticity profile of the pp
interaction, with, curiously, less absorption for the
head-on collisions than for collisions at a non-zero
impact parameter. We argue that the hollowness in the impact
parameter is a quantum effect; it precludes models of inelastic
collisions where inelasticity...

115. Off-shell fragmentation

Karoly Uermoessy (Hungarian Academy of Sciences (HU))

According to recent measurements, the mass of jets created in LHC energy pp collisions has broad fluctuation. Typically, the mean mass of a jet with transverse momentum 200-600 GeV/c is around 40-100 GeV/c^2, so the ratio (jet mass)/(jet energy) is of order 0.2. As this value is not negligibly small, as required for factorisation to be applicable, the virtualitis of partons created in the hard...
