The proton is a basic constituent of matter, but its fundamental properties like the radius are, in spite of all effort, still not understood properly. The measurements of the radius via interaction with electrons or muons yield significantly different results, leading to the so called proton radius puzzle.
To bring new insight into the observed discrepancy a new electron scattering...

The ratio method is a recent observable that has been proposed for the study of halo nuclei [1]. It consists of the ratio of breakup angular distribution and the summed angu- lar distribution (which includes elastic, inelastic and breakup) and removes the reaction model dependence. Originally, this method was developed for high and intermediate ener- gies and studies of the reactions of 11 Be...

The BESIII experiment at the electron positron collider BEPCII
in Beijing is successfully operating since 2008 and has collected large data samples in the tau-mass region, including the world’s largest data samples at the J/psi and psi’ resonances. In particular decays of these two resonances provide a rich
and clean environment to study hadrons consisting out of light quarks and search...

Electron-Scattering-Experiments offer a deep insight into nuclear structure. While elastic Electron-Scattering is a technique used to determine the charge-radius of nuclei, the study of resonances or excited states can be used to test effective-field theories in a perturbative frame.
Especially in the last years further progress was made in this field by performance of ab-initio calculations...

In this study we model early times dynamics of relativistic heavy ion collisions by an initial color electric field which then decays to a plasma by the Schwinger mechanism, coupling the dynamical evolution of the initial color field to the dynamics of the many particles system produced by the decay. The latter is described by relativistic kinetic theory in which we fix the ratio $eta/s$...

The picosecond pulse of quasi-monoenergetic high-energy neutrons is produced in each interaction of relativistic heavy nuclei in light target. The energy and angular distributions of the neutrons for Pb + 1H and Pb + C collisions are estimated using Lorentz transformation of a Moving Source Model fit to the neutron data for reactions p + Pb and C + Pb at GeV energies. The analysis of neutron...

Hard partons produced in the early stage of high-energy heavy-ion collisions suffer energy loss in the Quark-Gluon Plasma (QGP) via gluon radiation and elastic collisions while propagating through this medium. Jet reconstruction provides access to the kinematics of these partons. Reconstructed jets are therefore powerful tools to study the properties of the QGP. Theoretical models predict a...

The recent hyperon-nucleon/nuclei correlation studies performed by the AMADEUS collaboration might reveal unprecedent informations on the K- low-energy interaction with light nuclei thanks to the unique kaon beam provided by the DAFNE collider and the excellent features of the KLOE detector. The Lp and the S0p final states, produced in the K- absorption processes on 12C and 4He, were analyzed....

The BESIII Experiment collected large data samples for electron-positron collisions with center-of-mass above 4 GeV during 2013 and 2014. The analysis of these samples has resulted in a number of surprising discoveries, such as the discoveries of the electrically charged 'Zc' structures, which, if resonant, cannot be accomodated in the traditional charm quark and anti-charm quark picture of...

The Big Bang Nucleosynthesis (BBN) describes the production of light nuclides in the first minutes of cosmic time. It started with deuterium accumulation when the Universe was cold enough to allow 2H nuclei to be survived to photo-disintegration.
A primordial deuterium abundance evaluation D/H=(2.65±0.07)×10^(-5) [1] is obtained by merging BBN calculations and CMB analysis obtained by the...

The continuum of electron-positron pairs, produced in heavy ion collisions, provides an excellent
probe of the quark-gluon plasma. To extract possible signatures, it is important to work with an
electron sample of high purity. Dielectrons are also studied in proton-proton collisions to provide a
crucial reference.
