<title>RADPyC2026</title>
<description>The Division of Particles and Fields of the Mexican Physical Society (DPyC-SMF) organizes every year the Annual Meeting (RADPyC). This space is dedicated mainly for the exposure of results of graduate students and young researchers working in high energy physics and includes some review talks on the hot topics of the field. This year the meeting will be held in Auditorio José Ádem, Cinvestav, Mexico City, México. The scientific programme will consist of invited and contributed talks, and a poster session. It will begin in the morning of Wednesday 17 June and end before lunch on Friday 19 June.

We will have the following invited talks:
 
- Ana Colmenero, HAWC (UMSNH)

- Jens Erler, The EW SM and constraints on NP (Mainz, PRISMA)

- Iván Martínez Soler, Neutrino physics (Durham Univ.)

- Cristina Oropeza, CMS (Ibero)

- Antonio Ortiz, ALICE (ICN-UNAM)

- Gabriel Palacios, Accelerator physics (UNAM)

- Antonio Pich, Flavor physics (IFIC)

- Pedro Podesta, Belle-II (UAS)

- Selomit Ramírez, QCD, Loop Tree Duality, Quantum Computing (UAS)

- Saúl Ramos, Flavor physics from a top-down perspective (IF-UNAM)

- Alfredo Raya, NICA (UMSNH)

- Eric Vázquez, DM-neutrinos (exp.) (IF-UNAM)


The whole event can be followed by Zoom:

 <abstract>The worldline formalism offers an alternative framework to the standard diagrammatic approach in quantum field theory, based on first-quantized relativistic path integrals. Over recent decades, this formalism has attracted growing interest due to its potential applications and computational advantages. As a result, a collection of worldline master integrals has been derived within this approach. However, efficient mathematical tools for evaluating these integrals remain limited.

Motivated by unitarity methods used in the conventional formalism of quantum field theory, this talk proposes a novel framework for evaluating one-loop worldline master integrals, up to a rational function in the kinematical external invariants, through the computation of their discontinuities. Similarly to standard unitarity techniques, the method involves decomposing an $n$-point one loop amplitude in $D=4$ dimensions into a linear combination of tadpole, bubble, triangle, and box master integrals. The coefficients of this decomposition are rational functions of the external kinematic invariants determined by the discontinuities of the corresponding worldline master integrals.</abstract>
