Influence of magnetic field on beta-processes in supernova matter

Alexandra Dobrynina, Igor Ognev

An influence of a magnetic field on beta-processes is investigated under conditions of a core-collapse supernova. For realistic magnetic fields reachable in astrophysical objects w…

Interpretation of $Y_{b} (10750)$ as a tetraquark and its production mechanism

Ahmed Ali, Luciano Maiani, Alexander Ya. Parkhomenko +1

Recently, the Belle Collaboration has updated the analysis of the cross sections for the processes $e^{+} e^{-} \to Υ (n S) π^{+} π^{-}$ ( $n = 1, 2, 3$ ) in the $e^{+} e^{-}$ center-of-mass…

Thompson-like characterization of solubility for products of finite groups

P. Hauck, L. S. Kazarin, A. Martínez-Pastor +1

A remarkable result of Thompson states that a finite group is soluble if and only if its two-generated subgroups are soluble. This result has been generalized in numerous ways, and…

On the $3 D$ consistency of a Grassmann extended lattice Boussinesq system

Sotiris Konstantinou-Rizos

In this paper, we formulate a "Grassmann extension" scheme for constructing noncommutative (Grassmann) extensions of Yang-Baxter maps together with their associated systems of P $Δ$ …

Mass spectrum of the hidden-charm pentaquarks in the compact diquark model

Ahmed Ali, Ishtiaq Ahmed, M. Jamil Aslam +2

The LHCb collaboration have recently updated their analysis of the resonant $J / ψ p$ mass spectrum in the decay $Λ_{b}^{0} \to J / ψ p K^{-}$ , making use of their combined Run 1 and Run 2 dat…

Entwining Yang-Baxter maps related to NLS type equations

S. Konstantinou-Rizos, G. Papamikos

We construct birational maps that satisfy the parametric set-theoretical Yang-Baxter equation and its entwining generalisation. For this purpose, we employ Darboux transformations…
