Title: On the $\gamma\gamma$ ExcessComments: 29 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just seen a resonance in the latest LHC data at 4.2 sigma. Therefore, vector-like fermions are added to minimal composite Higgs to explain the $\gamma\gamma$ resonance. The $\eta$ couples to $b\bar{b}$, but not to $Z\gamma$, alleviating tension with Run 1. Curiously, vector-like fermions are required at 700 GeV. Finally, we scrutinize the $\gamma\gamma$ peak in the MSSM with new gauge interactions.

Title: The $\gamma\gamma$ Resonance as a Pseudo Nambu Goldstone BosonComments: 16 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this letter, we discuss the very recent diphoton excess at run 2 and muon g-2. Consequently, we consider the diphoton peak in left-right models on 3-brane. The conformal symmetry stabilizes the mass of the $S(750)$. Therefore, vector-like quarks at 900 GeV should be observed soon. We will provide more details in a future paper.

Title: Is It Wide? Calculating the NLO Cross Section in 2HDMsAuthors: V. LiComments: 29 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this letter, we look at the intriguing diphoton peak at run 2 (at 4.0 sigma). Interestingly, we study the phenomenology of left-right models and calculate the full mass spectrum. In short, the PQ symmetry stabilizes the mass of the resonance. Assuming the diphoton resonance is real, we predict that exotic fermions should be at 700 GeV. More data is likely to confirm this perplexing truth.

Title: Interpretations of the 750 GeV Peak in Twin HiggsComments: v4: 21 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this letter, we look at the recent diphoton excess at run 2 and natural inflation. Actually, we study the $\gamma\gamma$ resonance in minisplit SUSY models with vector-like fermions. The chiral symmetry protects the mass of the $S$. In short, we predict a heavy pion below 900 GeV. We leave the rest for future study.

Title: The Diphoton Excess From Pati-Salam ModelsComments: v2: 19 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just observed a resonance in run 2 of the LHC. Unfortunately, the diphoton anomaly is analyzed in SU(3)^3 with conformal dynamics. Consequently, a downside of this model is that $Z\gamma$ and $t\bar{t}$ are predicted to be sizable. Neutralinos are required at 500 GeV. Consequently, there is much to be done.
