In Heavy Ion Collisions (HIC) at Fermi energies (10 MeV/nucleon ≤ E/A ≤ 100 MeV/nucleon) hot nuclear systems are produced and they may disassemble by a variety of dynamical and statistical mechanisms with vastly different time scales (neck emission, fission, multifragmentation, fusion-evaporation, ecc.).
The space-time sensitivity of the fragment-fragment Correlation Function to the...

The production and properties of $K^0_S$, $K^+$, $\Phi$ and $K^-$ in cold nuclear matter generated in pion-nucleon reactions ($\pi^- + A$, $A = C, W$) at $p_{\pi^-}= 1.7$ GeV/c has been investigated with the HADES detector at GSI.
Similar to the $K^0$ production at the surface of the nuclei ($\sigma \sim A^{b}, b=2/3$), as already verified by the FOPI collaboration, it was assumed to apply...

Short Contribution
Over the past two decades, a discrepancy has emerged between two
different techniques for measuring the proton's electromagnetic
form factors. Unpolarized electron-proton cross section measurements
paint a picture of the proton's internal structure that is incompatible
with measurements from polarization transfer experiments. The leading
hypothesis is that the discrepancy is caused by a...

The suppression of Y mesons in the hot quark-gluon medium (QGP) versus reduced feed-down is investigated in UU collisions at RHIC energies and PbPb collisions at LHC energies. Our centrality- and p_T-dependent model encompasses screening, collisional damping and gluodissociation in the QGP. For Y(1S) it is in agreement with both STAR and CMS data provided the relativistic Doppler effect and...

A measurement of the ratio $P_x/P_z$ of polarization transfer components in the $\mathrm{D}(\vec{e},e'\vec{p})n$ reaction at different missing momenta will be reported.
The $P_x/P_z$ ratio observed for H, D, and $\mathrm{^{4}He}$, respectively, indicates a dependency on the proton's virtuality and the missing momentum direction, but not the average nuclear density.
