Abstract: We present a flavour non-universal extension of the Standard Model combined with the idea of Higgs compositeness. At the TeV scale, the gauge groups SU(2)R and U(1)B−L are assumed to act in a non-universal manner… read more here.

DOI: 10.1007/jhep01(2025)132
Abstract: If dark matter carries a baryon number of two, neutron-antineutron oscillations could require its presence to manifest themselves. If it is in addition very light, in the micro-eV range or up to a few orders… read more here.

DOI: 10.1007/jhep01(2025)147
Abstract: In this paper, we investigate minimal scalar leptoquark models that dynamically generate neutrino Majorana masses at the one-loop level and examine their implications for low-energy processes. We show that these models can produce viable neutrino… read more here.

Abstract: We investigate holographic complexities in the context of wedge holography, focusing specifically on black string geometry in AdS3. The wedge spacetime is bounded by two end-of-the-world (EOW) branes with intrinsic Dvali-Gabadadze-Porrati (DGP) gravity. In line… read more here.
