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

A short review on QCD sum rule studies of $$P$$ -wave single heavy baryons
AAPPS BulletinIn recent decades, the spectroscopy of singly heavy baryons has made significant progress, with many excited states observed experimentally. Among the various theoretical approaches used to study their properties, the QCD sum rule method has been widely ...

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.

The imprint of conservation laws on correlated particle production
Journal of High Energy PhysicsThe study of event-by-event fluctuations of net-baryon number in a subspace of full phase space is a promising direction for deciphering the structure of strongly interacting matter created in collisions of relativistic heavy nuclei.

Beam energy dependence of net-hyperon yield and its implication on baryon transport mechanism
Physics Letters BIn the constituent quark model, each quark inside a baryon carries 1/3 unit of the baryon number. An alternative picture exists where the center of a Y-shaped topology of gluon fields, called the baryon junction, carries a unit baryon number.

Interactions and decays of high-spin baryon resonances
EPJ Web of Conferences, 2012 Understanding strong interactions at low energy region requires the precise knowledge on the spectra and the properties of hadrons. Such informations can be obtained through detailed and sophisticated analyses of experimental data collected from various ...

Cluster production and the pomeron in meson-baryon and baryon-baryon collisions
Physics Letters B, 1975 Abstract The bare pomeron in models based on duality diagrams is found to contribute very differently at low energies to pp and Kp total cross-sections. A simple quantitative comparison of these cross-sections is found to be consistent with phenomenological cluster production models.

, 2017 Baryons are considered to be intricate particles having real geometrical structure, based on our previous proton design. Inherent baryon spin is proportional to mass and radius. The well-known octets and decuplets fit into groups where mass-squared and quantised-action are related.

Symmetries of Baryons and Mesons [PDF]
Physical Review, 1962 The system of strongly interacting particles is discussed, with electromagnetism, weak interactions, and gravitation considered as perturbations. The electric current jα, the weak current Jα, and the gravitational tensor θαβ are all well-defined operators, with finite matrix elements obeying dispersion relations.

Novel phases of a baryon-dense QCD-like theory
Journal of High Energy PhysicsWe investigate the phases of a strongly coupled QCD-like theory at finite baryon chemical potential using s-confining supersymmetric QCD deformed by anomaly-mediated supersymmetry breaking.
