Title: On the 750 GeV AnomalyComments: 26 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just seen a resonance in the 13 TeV data at 3.9 sigma. Surprisingly, we consider the phenomenology of two Higgs doublet models and predict the statistical significance. The $S$ couples to $hh$, but not to $b\bar{b}$, alleviating tension with Run 1. Charge 2/5 quarks at 400 GeV should be observed soon. More data is likely to confirm this unforseen framework.

Title: Explaining the Diphoton Excess and the Doublet-triplet Splitting ProblemAuthors: U. GersdorffComments: v2: updated figure 3, conclusions unchanged, no figuresSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this letter, we look at the intriguing diphoton anomaly at run 2 (at 1.0 sigma). Surprisingly, we scrutinize the phenomenology of GUT models and compute mass ratios. Curiously, the R symmetry protects the mass of the $\phi$. We predict a pion below 900 GeV. Finally, we study the phenomenology of composite twin Higgs and compute the full mass spectrum.

Title: A Common Framework for the $\gamma\gamma$ Anomaly and $h \to \mu \tau$Authors: H. Raychaudhuri, X. Yu, K. Tesi, G. Marzocca, L. Sadhukhan, A. No, D. Mandal, V. Dutta, K. Okada, J. OmuraComments: v4: 44 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
ATLAS and CMS have just seen a resonance in run 2 of the LHC at 3.7 sigma. Consequently, although the 750 GeV anomaly could be a statistical fluctuation, we scrutinize the phenomenology of E6 and analyze mass ratios. A downside of this model is that $hh$ and $b\bar{b}$ are predicted to be large. Thus, colored pions are required at 900 GeV. Given this, our work may seem quite deep.

Title: The 750 GeV Excess as a Pseudo Nambu Goldstone BosonComments: v4: 3 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this paper, we discuss the recent diphoton anomaly at run 2 (at 3.0 sigma). Surprisingly, we consider the $\gamma\gamma$ excess in the NMSSM on warped metric. The $X$ couples to $WW$, but not to $WW$, worsening tension with Run 1. Remarkably, the diphoton anomaly implies neutral fermions around 900 GeV. Our results are similar to work done by Quevillon and Sengupta.

Title: The $\gamma\gamma$ Resonance From GUT ModelsComments: 4 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
Less than a year ago, ATLAS and CMS have reported a peak in run 2 of the LHC. Unsurprisingly, we study the diphoton resonance in the broken MRSSM on AdS_5. The flavor symmetry protects the mass of the $\eta$. Interestingly, we predict a heavy pion below 600 GeV. Our results are similar to work done by Fan and Chiang.
