Fortschritte der Physik, Volume 73, Issue 3, March 2025.Abstract Current observations show that a significant fraction of the Universe is composed of dark energy and dark matter. In this paper, the simultaneous effects of these dark sectors on the Euler–Heisenberg black hole are investigated, using the quintessence matter field and perfect fluid to model them. In particular, the black hole's thermodynamics,

Aharonov–Bohm protection of black hole's baryon/skyrmion hair
Physics Letters B, 2017 The baryon/skyrmion correspondence implies that the baryon number is encoded into a topological surface integral. Under certain conditions that we clarify, this surface integral can be measured by an asymptotic observer in form of an Aharonov–Bohm phase ...

Generation of SU(3) sum rule for charmed baryon decay
Journal of High Energy Physics, 2022 Flavor SU(3) symmetry is a powerful tool to analyze charmed baryon decays. In this work, we propose an approach to generate SU(3) sum rules for the singly and doubly charmed baryon decays without writing the Wigner-Eckhart invariants explicitly. The SU(3)

Baryon Binding Energy in Sakai-Sugimoto Model
, 2009 The binding energy of baryon has been studied in the dual $AdS_5\times S^5$ string theory with a black hole interior. In this picture baryon is constructed of a $D_5$ brane vertex wrapping on $S^5$ and $N_c$ fundamental strings connected to it.

Visible GeV ALP from TeV Vector‐Like Leptons
Fortschritte der Physik, Volume 73, Issue 3, March 2025.Abstract A model is presented where a GeV axion‐like‐particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei–Quinn (PQ) symmetry‐breaking terms in an exotic leptonic sector. The latter provides a solution to the muon g−2$g-2$ anomaly, within the framework of the Linear Seesaw neutrino mechanism.

Effects of three-baryon forces on kaon condensation in hyperon-mixed matter
Physics Letters B, 2021 Possibility of kaon-condensed phase in hyperon-mixed matter is considered on the basis of chiral symmetry for kaon-baryon and kaon-kaon interactions, being combined with the relativistic mean-field theory for two-body baryon interaction.

Studies of final state interactions via femtoscopy in ALICE
, 2016 Femtoscopy is a technique enabling measurements of the space-time characteristics of particle-emitting sources. However, the femtoscopic analysis is also sensitive to the interaction cross-section. In this paper we show the first preliminary measurements

Recent Developments in Degenerate Higher Order Scalar Tensor Theories
Annalen der Physik, Volume 537, Issue 2, February 2025.Degenerate Higher Order Scalar Tensor theories are reviewed, together with their applications in cosmology and astrophysics. These theories have been applied to build models of the early universe, in the description of the late‐time cosmic acceleration, as well as in astrophysics, including black hole physics. They have the potential to provide answers
