Correlation between mean transverse momentum and anisotropic flow in models at NICA energy range30m
The elliptic flow is one of the key observables sensitive to the transport properties of the strongly interacting matter formed in relativistic heavy-ion collisions. In addition for a more precision extraction of the specific shear viscosity of the strongly interacted matter, the partial correlation coefficient between the mean transverse momentum and the anisotropic flow can be used. In our work we study the centrality dependence of the correlation coefficient of charged hadrons produced in Au+Au collisions in the different models at NICA energy range.
Relativistic partial wave analysis of inclusive meson production A + B =⇒ V + X =⇒ 1 + 2 + X and determination of the spin quantization axis via the cross sections A + B =⇒ V + X30m
Relativistic amplitudes, cross sections and angular distributions which explicitly dependent on orbital moments and spin of intermediate V -meson resonance in inclusive reactions A + B ⇒ V + X ⇒ 1 + 2 + X are constructed are constructed. It is shown that spin quantization axis of the particles in the final states can be determined through the cross sections or spin density matrix of reaction A+B ⇒ V + X. Some key experimental data with alignment of the final particles 1 and 2 are demonstrated.
