Perturbative RGE systematics in precision observables

Autor: Bertone, Valerio, Bozzi, Giuseppe, Hautmann, Francesco

QCD calculations for collider physics make use of perturbative solutions of renormalisation group equations (RGEs). Ambiguities related to these solutions can contribute significantly to systematic uncertainties of theoretical predictions for physica

Revisiting Primordial Black Hole Capture by Neutron Stars

Autor: Caiozzo, Roberto, Bertone, Gianfranco, Kühnel, Florian

Publikováno v: Journal of Cosmology and Astroparticle Physics, Volume 2024, July 2024

A sub-solar mass primordial black hole (PBH) passing through a neutron star, can lose enough energy through interactions with the dense stellar medium to become gravitationally bound to the star. Once captured, the PBH would sink to the core of the n
