<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>Light-by-light scattering, a purely quantum and nonlinear prediction of Quantum Electrodynamics (QED), has represented both a theoretical and experimental challenge since the formulation of the Heisenberg-Euler effective action. In this talk, a historical review of the development of QED will be presented, focusing on the phenomenon of light-by-light scattering. Subsequently, the Worldline Formalism will be introduced as a robust alternative to perturbation theory based on Feynman diagrams. The computational advantages of this method for simplifying the calculation of scattering amplitudes will be highlighted. Finally, an overview of the experimental efforts to measure this elusive effect will be offered, ranging from the earliest searches to the current research frontier using ultra-high intensity lasers at facilities such as the Center for Advanced Laser Applications (CALA)</abstract>
