| dc.description.abstract | [EN]We compute the next-to-leading order (NLO) QCD corrections to the 1 → 2 splitting amplitudes in different dimensional regularization (DREG) schemes. Besides recovering previously known results, we explore new DREG schemes and analyze their consistency by comparing the divergent structure with the expected behavior predicted by Catani’s formula. Through the introduction of scalar-gluons, we show the relation among splittings matrices computed using different schemes. Also, we extended this analysis to cover the double collinear limit of scattering amplitudes in the context of QCD + QED. [ES] Calculamos las correcciones de QCD a orden siguiente al líder (NLO) para las amplitudes de splitting 1 → 2 en distintos esquemas de regularización dimensional (DREG). Además de recuperar resultados previamente conocidos, exploramos nuevos esquemas DREG y analizamos su consistencia comparando la estructura divergente con el comportamiento esperado predicho por la fórmula de Catani. Mediante la introducción de gluones escalares, mostramos la relación entre las matrices de splitting calculadas usando distintos esquemas. Asimismo, extendemos este análisis para cubrir el límite doble colineal de las amplitudes de dispersión en el contexto de QCD + QED. | es_ES |
