<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>This mechanism aims to provide a solution to the hierarchy problem. To this end, it is based on a model with classical conformal invariance and a global custodial $SO(6)$ symmetry imposed at high energies. Quantum corrections break the conformal symmetry through the Coleman–Weinberg mechanism, dynamically generating a new scale and inducing vacuum expectation values for the scalar fields. The spontaneous breaking of the custodial symmetry gives rise to the Higgs boson as a pseudo-Nambu–Goldstone boson (pNGB), thereby protecting its mass from large radiative corrections. Interactions that explicitly break the custodial symmetry generate only small contributions to the Higgs mass, naturally leading to a hierarchy between the electroweak scale $v_H$ and the new dynamical scale $v_\Phi$, without requiring severe fine-tuning.</abstract>
