10. Axions, neutrinos, and Higgs-like resonances, a fuzzy combination

Prof. Eduardo Rojas (Universidad de Nariño.)

Carlos Vera

Recent results from several experimental collaborations have reported deviations from the Standard Model predictions in di-photon final states, suggesting the presence of intermediate scalar resonances above the electroweak scale. The wide variety of such anomalies can be naturally accommodated within extensions of the Standard Model that feature an enlarged scalar sector. In particular,...

9. Discrete Flavor Symmetries in Multi-Higgs Models

Myriam Mondragon

Eduardo Rojas

In this talk we review briefly the Standard Model, then we explain the role of symmetries in extensions of the Standard Model, with particular emphasis on multi-Higgs models. We also discuss some aspects of the interrelation between astroparticle physics and physics Beyond the Standard Model, like the matter-antimatter asymmetry and dark matter.

4. Families and Irreducible Anomaly-Free Sets for 3–3–3–1 Gauge Theories

Prof. Yithsbey Giraldo Usuga (Universidad de Nariño)

We present a model-agnostic scheme to assemble \textbf{quark--lepton families} within flipped trinification, $SU(3)_C\times SU(3)_L\times SU(3)_R\times U(1)_X$, allowing for arbitrary charge embeddings. The core of our construction is the identification and taxonomy of \textbf{Irreducible Anomaly-Free Sets (IAFS)}: minimal fermion multiplet combinations that, on their own, cancel all gauge and...

3. Gauge Symmetry in the Hamilton-Jacobi Formulation

German Ramos

This study determined the constraint structure of the gauge-symmetric Proca field using the Hamilton-Jacobi approach. We extracted the complete set of Hamiltonians from Frobenius’ integrability conditions, along with the characteristic equations. Functioning as canonical transformation generators, these Hamiltonians directly correspond to the generators of the Lagrangian gauge transformations....

5. Probing flipped trinification at colliders

Prof. Eduardo Rojas (Universidad de Nariño.)

We explore the recently proposed gauge symmetry
( SU(3)_C \otimes SU(3)_L \otimes SU(3)_R \otimes U(1)_X ),
which naturally embeds both the Left-Right symmetric model and the 3-3-1 model as subgroups. Within this unified framework, we propose four families of leptons and quarks. A detailed analysis of their contributions to gauge anomaly cancellation is carried out for a general value of...
