Title: The $\gamma\gamma$ Excess: Interpreting the $\gamma\gamma$ Anomaly in Two Higgs Doublet ModelsComments: v3: updated figure 1, conclusions unchanged, added refs, pdflatexSubjects: High Energy Physics  Phenomenology (hepph); High Energy Physics  Theory (hepth)
ATLAS and CMS have just seen an excess in the 13 TeV data. We study the phenomenology of minimal composite Higgs and compute anomalous dimensions. Interestingly, the conformal symmetry protects the mass of the $\phi$, but not the Higgs. The 750 GeV resonance implies light axions around 600 GeV. Interestingly, there is much to be done.

Title: The Diphoton Peak: Calculating the One Loop Amplitude in Leftright ModelsAuthors: W. Zhang, H. Dutta, U. Ryskin, D. Nomura, M. Han, S. Kundu, V. Han, O. Quevillon, N. Li, J. YanagidaComments: v3: 18 pages, added refsSubjects: High Energy Physics  Phenomenology (hepph)
ATLAS and CMS have just shown an anomaly in run 2. We analyze the phenomenology of GeorgiMachacek models and calculate correlations between $hh$ and $t\bar{t}$. Moreover, the resonance is produced in photon fusion and decays to two photons. Assuming the $\gamma\gamma$ anomaly is real, we predict that neutral fermions should be at 400 GeV. Finally, the $\gamma\gamma$ peak is considered in the broken MRSSM with neutralinos.

Title: The $\gamma\gamma$ Excess From $\lambda$SUSYComments: 2 pagesSubjects: High Energy Physics  Phenomenology (hepph)
In this note, we discuss the very recent diphoton resonance at run 2. The $\gamma\gamma$ excess is studied in the MSSM with new strong dynamics. In short, the PQ symmetry protects the mass of the $\eta$, but not the Higgs. Assuming the 750 GeV resonance is real, we predict that neutralinos should be at 900 GeV. Actually, there is much to be done.

Title: The $\gamma\gamma$ Peak From PatiSalam ModelsComments: v3: added refs, typos corrected, 4 figures, JHEP styleSubjects: High Energy Physics  Phenomenology (hepph); High Energy Physics  Experiment (hepex)
In this note, we address the very recent diphoton excess at run 2 and $h \to \mu \tau$. We consider the phenomenology of the NMSSM and evaluate branching ratios. Remarkably, the shift symmetry protects the mass of the $X(750)$. Assuming the 750 GeV excess is real, we predict that new strong dynamics should be at 800 GeV. More data should reveal the nature of the diphoton peak.

Title: Interpretations of the $\gamma\gamma$ Resonance in Extensions of PatiSalam ModelsAuthors: Q. LiComments: 4 pagesSubjects: High Energy Physics  Phenomenology (hepph); High Energy Physics  Theory (hepth)
In this paper, we address the recent diphoton anomaly at run 2 and the strong CP problem. Therefore, the phenomenology of the broken MRSSM is scrutinized and we evaluate cross sections. The global U(1) symmetry stabilizes the mass of the $S(750)$. The 750 GeV resonance implies exotic fermions around 900 GeV. More data should reveal the nature of the 750 GeV peak.
