Microscopic study of baryon stopping in low-energy heavy-ion collisions within UrQMD model

Sudhir Pandurang Rode

In low-energy heavy-ion collisions, baryon stopping is an important process, in which protons from the initial colliding nuclei are stopped at mid-rapidity region. Quantifying such…

Reentrance of proton-neutron pairing in hot nuclear systems

T. Vu Dong, Alan A. Dzhioev, A. I. Vdovin +1

We develop a generalized finite-temperature proton-neutron BCS framework using the superoperator formalism, incorporating both isovector and isoscalar monopole pairing channels. Nu…

Fresh Look at Polarized Deuterons at the Nuclotron/NICA \& HIAF and Beyond

B. Gou, V. P. Ladygin, N. N. Nikolaev +3

Being a spin-1 particle, the deuteron, when polarized, offers access to a wide range of interesting tensor observables. A quest for tensor asymmetries is at the heart of the spin p…

supersymmetric multiparticle systems based on indecomposable multiplets

Sergey Fedoruk, Evgeny Ivanov, Stepan Sidorov

We construct new multiparticle models of supersymmetric mechanics with spin degrees of freedom by employing nonlinear indecomposable supermultiplets ${\bf (1,4,3){\…

Multivariate amplitude analysis of the cascade particle decays based on the Nearest Neighbors fitting

I. V. Yeletskikh, A. O. Vasyukov

The Nearest Neighbors estimation of likelihood is implemented for the multivariate amplitude analysis of the cascades of particle decays. In this approach Monte Carlo simulated eve…

Microscopic Statistical Calculation of Nuclear Level Density Based on Relativistic Density Functional Theory

Zi-Cheng Wang, Peng-Xiang Du, Jian Li +2

A microscopic statistical model based on the relativistic density functional theory (RDFT) is developed to calculate the nuclear level density (NLD). The approach employs self-cons…
