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.

Das zirkumgalaktische Medium

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 ...

The imprint of conservation laws on correlated particle production

Journal of High Energy Physics
The 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.

Derivation of the Lorentz Transformations for Three‐Dimensional Relative Motion Between Inertial Frames of Reference

Advances in Mathematical Physics, Volume 2025, Issue 1, 2025.
Lorentz transformations are central to relativistic mechanics, explaining phenomena such as the mass–energy relationship, spatial contraction, momentum transformation, velocity addition, and the geometric structure of Minkowski space‐time. While traditionally derived for motion along a single spatial axis, these transformations can be generalized to ...

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.

Statistical Matrix for Electroweak Baryogenesis

, 1997
In electroweak baryogenesis, a domain wall between the spontaneously broken and unbroken phases acts as a separator of baryon (or lepton) number, generating a baryon asymmetry in the universe.

Heavy Quarkonium States With Baryonic Chemical Potential

Advances in High Energy Physics, Volume 2025, Issue 1, 2025.
In this work, we have studied the dissociation behavior of 1S and 2S states of quarkonium using quasiparticle approach where the Debye mass depends on baryonic chemical potential. The binding energies of the quarkonium states has been obtained by using quasiparticle Debye mass which further depends on temperature and baryonic chemical potential (μb ...

Strangeness S=-3 and -4 baryon-baryon interactions in chiral EFT

, 2010
I report on recent progress in the description of baryon-baryon systems within chiral effective field theory. In particular, I discuss results for the strangeness S=-3 to -4 baryon-baryon systems, obtained to leading order.Comment: 4 pages, 2 figures ...

Beam energy dependence of net-hyperon yield and its implication on baryon transport mechanism

Physics Letters B
In 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 ...
