Astroparticle Physics > 2018 > 97 > C > 1-9

The upcoming Cherenkov Telescope Array (CTA) project is expected to provide unprecedented sensitivity in the low-energy ( ≲ 100 GeV) range for Cherenkov telescopes. Most of the remaining background in this energy range results from misidentified hadron showers. In order to fully exploit the potential of the telescope systems it is worthwhile to look for ways to further improve the available analysis...

A relation between the Barbero–Immirzi parameter and the standard model

Bogusław Broda, Michał Szanecki

Physics Letters B > 2010 > 690 > 1 > 87-89

It has been shown that Sakharov's induced, from the fields entering the standard model, Barbero–Immirzi parameter γ assumes, in the framework of Euclidean formalism, the UV cutoff-independent value, 1/9. The calculus uses the Schwinger's proper-time formalism, the Seeley–DeWitt heat-kernel expansion, and it is akin to the derivation of the ABJ chiral anomaly in space–time with torsion.

Induced gravity and gauge interactions revisited

Bogusław Broda, Michał Szanecki

Physics Letters B > 2009 > 674 > 1 > 64-68

It has been shown that the primary, old-fashioned idea of Sakharov's induced gravity and gauge interactions, in the “one-loop dominance” version, works astonishingly well yielding phenomenologically reasonable results. As a byproduct, the issue of the role of the UV cutoff in the context of the induced gravity has been reexamined (an idea of self-cutoff induced gravity). As an additional check, the...

Quantization of four-dimensional Abelian gravity

Bogusław Broda, Piotr Bronowski, Marcin Ostrowski, Michał Szanecki

Physics Letters B > 2007 > 655 > 3-4 > 178-182

An Abelian version of standard general relativity in the Cartan–Palatini gauge-like formulation in four dimensions has been introduced. Traditional canonical analysis utilizing similarities to the akin Husain–Kuchař SU(2) version of gravity has been performed. The model has been next quantized in the canonical path-integral Faddeev–Popov formalism yielding Abelian BF theory.
