Constraints on the fermionic dark matter from observations of neutron stars
V. Sagun, E. Giangrandi, O. Ivanytskyi +2
We study an impact of asymmetric fermionic dark matter on neutron star properties, including tidal deformability, mass, radius, etc. We present the conditions at which dark matter…
Neutron stars: new constraints on asymmetric dark matter
O. Ivanytskyi, V. Sagun, I. Lopes
We study an impact of asymmetric dark matter on properties of the neutron stars and their ability to reach the two solar masses limit, which allows us to present a new range of mas…
Primordial black-hole formation and heavy r-process element synthesis from the cosmological QCD transition. Two aspects of an inhomogeneous early Universe
M. Gonin, G. Hasinger, D. Blaschke +2
We review the role of primordial black holes (PBHs) for illuminating the dark ages of the cosmological evolution and as dark matter candidates. We elucidate the role of phase trans…
Tetraneutron condensation in neutron rich matter
O. Ivanytskyi, M. Ãngeles Pérez-GarcÃa, C. Albertus
In this work we investigate the possible condensation of tetraneutron resonant states in the lower density neutron rich gas regions inside Neutron Stars (NSs). Using a relativistic…
Thermodynamics of quark matter with multiquark clusters in an effective Beth-Uhlenbeck type approach
D. Blaschke, M. Cierniak, O. Ivanytskyi +1
We describe multiquark clusters in quark matter within a Beth-Uhlenbeck approach in a background gluon field coupled to the underlying chiral quark dynamics using the Polyakov gaug…
Second look to the Polyakov Loop Nambu-Jona-Lasinio model at finite baryonic density
O. Ivanytskyi, M. Ãngeles Pérez-GarcÃa, V. Sagun +1
We revisit the Polyakov Loop coupled Nambu-Jona-Lasinio model that maintains the Polyakov loop dynamics in the limit of zero temperature. This is of interest for astrophysical appl…
Quark deconfinement in compact stars through sexaquark condensation
D. Blaschke, O. Ivanytskyi, M. Shahrbaf
In this contribution, we present for the first time a scenario according to which early quark deconfinement in compact stars is triggered by the Bose-Einstein condensation (BEC) of…
Statistical Multifragmentation Model Within the Extended Morphological Thermodynamics Approach
V. S. Kucherenko, K. A. Bugaev, V. Sagun +1
On the basis of morphological thermodynamics we develop an exactly solvable version of statistical mutifragmentation model for the nuclear liquid-gas phase transition. It is shown…
Status and initial physics performance studies of the MPD experiment at NICA
MPD Collaboration, V. Abgaryan, R. Acevedo Kado +470
The Nuclotron-base Ion Collider fAcility (NICA) is under construction at the Joint Institute for Nuclear Research (JINR), with commissioning of the facility expected in late 2022.…
Inclusive J/psi production in pp collisions at sqrt(s) = 2.76 TeV
ALICE Collaboration, B. Abelev, J. Adam +966
The ALICE Collaboration has measured inclusive J/psi production in pp collisions at a center of mass energy sqrt(s)=2.76 TeV at the LHC. The results presented in this Letter refer…
