Parton distribution effects in the direct photon production at hadron collisions

David F. Rentería-Estrada, Roger J. Hernández-Pinto, German F. R. Sborlini

Parton distribution functions are crucial to understand the internal kinematics of hadrons. There are currently a large number of distribution functions on the market, and thanks t…

Four-loop scattering amplitudes journey into the forest

Selomit Ramírez-Uribe, Roger J. Hernández-Pinto, Andrés E. Rentería-Olivo +4

We present an overview of the analysis of the multiloop topologies that appear for the first time at four loops and the assembly of them in a general expression, the NMLT unive…

Elucidating the internal structure of hadrons through direct photon production

David F. Rentería-Estrada, Roger J. Hernández-Pinto, German F. R. Sborlini

The accurate description of the internal structure of hadrons is a very challenging task. In order to compare the predictions with the highly-accurate experimental data, it is nece…

Geometry and causal flux in multi-loop Feynman diagrams

German F. R. Sborlini

In this review, we discuss recent developments concerning efficient calculations of multi-loop multi-leg scattering amplitudes. Inspired by the remarkable properties of the Loop-Tr…

Geometry and causality for efficient multiloop representations

German F. R. Sborlini

Multi-loop scattering amplitudes constitute a serious bottleneck in current high-energy physics computations. Obtaining new integrand level representations with smooth behaviour is…

Analysis of the internal structure of hadrons using direct photon production

David F. Rentería-Estrada, Roger J. Hernández-Pinto, German F. R. Sborlini

Achieving a precise description of the internal structure of hadrons is a hard task, since there are several bottlenecks to obtain theoretical predictions starting from first princ…
