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

Possible molecular dibaryons with csssqq quarks and their baryon–antibaryon partners
European Physical Journal C: Particles and Fields, 2023 In this work, we systematically investigate the charmed–strange dibaryon systems with csssqq quarks and their baryon–antibaryon partners from the interactions $$\varXi ^{(',*)}_{c}\varXi ^{(*)}$$ Ξ c ( ′ , ∗ ) Ξ ( ∗ ) , $$\varOmega ^{(*)}_c\varLambda ...

, 2006 We perform the quenched lattice QCD analysis on the nuclear force (baryon-baryon interactions). We employ $20^3\times 24$ lattice at $\beta=5.7$ ($a\simeq 0.19$ fm) with the standard gauge action and the Wilson quark action with the hopping parameters ...

Baryon number segregation at the end of the cosmological quark-hadron transition [PDF]
, 1996 One of the most interesting questions regarding a possible first order cosmological quark--hadron phase transition concerns the final fate of the baryon number contained within the disconnected quark regions at the end of the transition.

A Brief, Biased View of Neutron Star Cooling
Astronomische Nachrichten, Volume 346, Issue 1, January 2025.ABSTRACT This is a concise and non‐technical review of topics related to neutron star (NS) cooling, for both young NSs and NSs in low‐mass x‐ray binaries. Neutrino emission from the NS core drives cooling rates, via different processes including Urca processes and pair breaking and formation at the neutron superfluid critical temperature.

Physik in unserer Zeit, Volume 56, Issue 1, Page 30-37, January 2025.Galaxien wie die Milchstraße sind umhüllt von einem gigantischen Kokon aus diffusem Gas. Aktuelle Forschungsergebnisse belegen, dass dieses zirkumgalakische Medium eine entscheidende Rolle für die Entstehung und Entwicklung von Galaxien spielt. Zusammenfassung Als zirkumgalaktisches Medium bezeichnet man die gasförmigen Hüllen von Galaxien, die sich ...

Gravitational baryogenesis in non-minimal kinetic coupling model
European Physical Journal C: Particles and Fields, 2023 In this work, we consider the gravitational baryogenesis in the framework of non-minimal derivative coupling model. A mechanism to generate the baryon asymmetry based on the coupling between the derivative of the Ricci scalar curvature and the baryon ...

Tensor Condensate Accompanied by Chiral Transition in a Strong Magnetic Field
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.We investigate tensor condensates and chiral condensates in the (2 + 1)‐flavor Nambu–Jona–Lasinio model at finite temperature and density in the presence of a strong magnetic field. The emergence of the tensor condensate is attributed to the four‐fermion interaction.
