Phase-space integrals through Mellin-Barnes representation
Taushif Ahmed, Syed Mehedi Hasan, Andreas Rapakoulias
We compute angular phase-space integrals with three and four denominators analytically, working within dimensional regularisation via the Mellin-Barnes (MB) representation. The app…

Angular phase-space integrals with four denominators through Mellin--Barnes
Taushif Ahmed, Syed Mehedi Hasan, Andreas Rapakoulias
We compute four-denominator angular phase-space integrals using the Mellin--Barnes (MB) technique in dimensional regularisation. Independent of the scattering process, an angular i…

Phase-space integrals through Mellin-Barnes representation
Taushif Ahmed, Syed Mehedi Hasan, Andreas Rapakoulias
This letter introduces a novel analytical approach to calculating phase-space integrals, crucial for precision in particle physics. We develop a method to compute angular component…
