DOI: 10.1007/jhep04(2020)061
Abstract: Within the premise of canonical quantisation, we re-examine the quantum structure of bosonic tensionless string theory. In the classical theory, the worldsheet metric degenerates and the Bondi-Metnzer-Sachs (BMS) algebra arises as the residual symmetries on… read more here.

DOI: 10.1007/jhep08(2024)001
Abstract: We study QCD vacuum structure with the topological θ angle using a recently proposed semiclassical approach on ℝ2 × T2 with the ’t Hooft and baryon magnetic fluxes. Under the assumption of adiabatic continuity in… read more here.

Abstract: A bstractIt is believed that in SU(N) Yang-Mills theory observables are N -branched functions of the topological θ angle. This is supposed to be due to the existence of a set of locally-stable candidate vacua,… read more here.

DOI: 10.1103/physrevd.111.034006
Abstract: We discuss the central and, mostly, spin-dependent potentials in heavy quarkonia b¯b,c¯c, with two goals in mind. The first is phenomenological: using the splitting between the 1S and 2S pairs, as well as the 1P… read more here.
