Chemical Evolution of the Universe and its Consequences for Gravitational‐Wave Astrophysics
Annalen der Physik, Volume 536, Issue 2, February 2024.Population properties of double compact object mergers (especially binary black holes) are sensitive to the metallicity dependent cosmic star formation history. The uncertainty of this quantity cannot be ignored and makes the interpretation of current gravitational wave observations difficult.

B to Baryon decays in Belle [PDF]
arXiv, 2006 We report recent observations of baryonic B decays with charmless and charmed baryons in the final state. We show the angular distributions of the di-baryon low-mass enhancements in the charmless three-body baryonic B decays andthe branching fractions of B decays with two charmed baryons or charmonium in the final states. We also report the observation

Heavy Elements and Electromagnetic Transients from Neutron Star Mergers
Annalen der Physik, Volume 536, Issue 2, February 2024.Astro‐(physics) has made major leaps forward through the combined information provided by both gravitational waves and electromagnetic emission from the first detected neutron star merger event. This review provides an up‐to‐date overview of today's understanding of neutron star mergers and their electromagnetic emission and it discusses possible ...

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 ...

Astronomische Nachrichten, Volume 345, Issue 2-3, February-March 2024.Abstract This paper focuses on the implications of a commutative formulation that integrates branch‐cutting cosmology, the Wheeler–DeWitt equation, and Hořava–Lifshitz quantum gravity. Building on a mini‐superspace structure, we explore the impact of an inflaton‐type scalar field on the wave function of the Universe.

Heavy Baryons: Current, Pion and Photon Transtions [PDF]
arXiv, 1994 We discuss the structure of current-induced bottom baryon to charm baryon transitions, and the structure of pion and photon transitions between heavy charm or bottom baryons in the Heavy Quark Symmetry limit as ${\scriptstyle m_Q\rightarrow \infty}$. Our discussion involves the ground state $s$-wave heavy baryons as well as the excited $p$-wave heavy ...

Spin Polarisability of the Nucleon in the Heavy Baryon Effective Field Theory
, 2005 We have constructed a heavy baryon effective field theory with photon as an external field in accordance with the symmetry requirements similar to the heavy quark effective field theory.

Differential rotation in compact objects with hyperons and delta isobars
Astronomische Nachrichten, Volume 345, Issue 2-3, February-March 2024.Abstract Neutron stars may experience differential rotation on short, dynamical timescales following extreme astrophysical events like binary neutron star mergers. In this work, the masses and radii of differentially rotating neutron star models are computed.

Lattice QCD and Baryon-Baryon Interactions: HAL QCD Method
Frontiers in Physics, 2020 In this article, we review the HAL QCD method to investigate baryon-baryon interactions, such as nuclear forces in lattice QCD. We first explain our strategy in detail to investigate baryon-baryon interactions by defining potentials in field theories ...
