DOI: 10.1007/jhep01(2025)102
Abstract: We demonstrate that the propagator, derived from an Effective Field Theory (EFT) that incorporates Weinberg’s compositeness theorem, provides a more general formula for describing S-wave near-threshold states. By fitting the lineshape using this propagator, we… read more here.

DOI: 10.1007/jhep08(2020)018
Abstract: In the first-quantised worldline approach to quantum field theory, a long-standing problem has been to extend this formalism to amplitudes involving open fermion lines while maintaining the efficiency of the well-tested closed-loop case. In the… read more here.

Abstract: Abstract Two-Line Elements (TLEs) continue to be the sole public source of orbiter observations. The accuracy of TLE propagations through the Simplified General Perturbations-4 (SGP4) software decreases dramatically as the propagation horizon increases, and thus… read more here.

Abstract: We calculate one loop QCD Regge Field Theory (RFT) correction to the propagator of reggeized gluons basing on the QCD effective action of Lipatov, [1–6], and results of [7], where Dyson-Schwinger hierarchy of the equations… read more here.

Abstract: Using Laplace’s method, Green’s function of the operator ∂t−12∂x2+k2x−2+12ω2x2,k≥−14, ω≥0 is calculated in the half-space x > 0. Therefrom, we deduce the propagator of Schrodinger’s equation with the potential V(x) = kx−2 + ω2x2 for k≥34. read more here.
