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,...
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...
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...
