One of the most exciting and puzzling observations in ultrarelativistic
p+A reactions is the fairly large harmonic flow (such as v2(pT) and
v3(pT) coefficients). On one hand, the flow seems to be consistent with
hydrodynamic simulations [1], suggesting a high degree of thermalization
even in such very small collision systems. On the other hand, several
non-thermal mechanisms can also...
The measurement of
For this reason, data are available only for few energy points in pp, pA and AA collisions, in particular, the energy gap between 2 and 4 GeV
remains unexplored. Also, since
about...
Quarkonia are mesons formed of either a charm and anti-charm quark pair (
The availability at the LHC of the largest collision energy in pp collisions allows a significant advance in the measurement of
Two-particle correlations as a function of
In this talk, we report measurements of the correlations of identified particles and their...
The study of energy and multiplicity dependence of hadron production in proton-proton (pp) collisions provides a powerful tool to understand similarities and differences between small and large colliding systems. In this talk we present new mid-rapidity measurements of the
Azimuthal anisotropies such as the elliptic flow
We study subthreshold \Xi production in p+A collisions using a BUU type transport code. We propose new \Xi creation mechanisms in two-step processes via hyperon-nucleon collisions. Our calcultions are compared with results by the HADES (GSI, Darmstadt) experiment.
Studies of particle yields and azimuthal correlations for inclusive and identified charged particles are presented in small collision systems of pp and pPb at the LHC with the CMS detector. Charged pions, kaons, and protons are identified via their energy loss in the CMS silicon tracker. The pT spectra and integrated yields are studied as a function of multiplicity and center-of-mass energies....
