DOI: 10.1007/jhep05(2018)043

Abstract: A bstractWe consider unitary CFTs with continuous global symmetries in d > 2. We consider a state created by the lightest operator of large charge Q ≫ 1 and analyze the correlator of two light… read more here.

DOI: 10.1103/physrevd.100.054036

Abstract: The spectra of heavy quarkonia are studied in two approaches: with the use of the Afonin-Pusenkov representation of the Regge trajectory for the squared excitation energy $E^2(nl)$ (ERT), and using the relativistic Hamiltonian with the… read more here.

DOI: 10.1103/physrevd.98.064052

Abstract: We advocate for an alternative description of gravitational radiation from black holes based on complex angular momentum techniques (analytic continuation of partial wave expansions, duality of the ${\cal S}$-matrix and effective resummations involving its Regge… read more here.

DOI: 10.1103/physrevlett.128.132001

Abstract: The high-energy limit of gauge-theory amplitudes features both a Regge pole and Regge cuts. We show how to disentangle these, and hence how to determine the Regge trajectory beyond two loops. While the nonplanar part… read more here.

DOI: 10.1142/s0217751x25501520

Abstract: In this work, we investigate the mass spectra of doubly strange-doubly bottom (ssbb) and fully bottom (bbbb) tetraquark states using the framework of Regge phenomenology. By modeling these tetraquarks as bound diquark-antidiquark systems, we employ… read more here.
