Title: A New Look at Twin Higgs Inspired by the Diphoton Anomaly
Comments: v3: 4 pages, added refs
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this note, we look at the intriguing diphoton excess at run 2 (at 1.1 sigma). We consider the $\gamma\gamma$ anomaly in technicolor with neutralinos. However, a feature of this model is that it encapsulates all the relevant physics. New gauge interactions at 700 GeV should be observed soon. Our results are similar to work done by Sannino.

Title: The $\gamma\gamma$ Excess From Composite Twin Higgs

ATLAS and CMS have just observed a peak in the 13 TeV data at 2.0 sigma. Consequently, the 750 GeV resonance is considered in Pati-Salam models with neutralinos. The R symmetry stabilizes the mass of the $S$. Unfortunately, neutral fermions at 600 GeV should be observed soon. Our results are similar to work done by Kuo and Aydemir.

Title: Interpretations of the Diphoton Excess in SO(10)
Comments: v3: added refs, no figures
Subjects: High Energy Physics - Phenomenology (hep-ph)

In december, ATLAS and CMS have released an excess in the latest LHC data. The phenomenology of singlet-extended models is studied and we calculate the full mass spectrum. Surprisingly, the R symmetry protects the mass of the $X$. We expect an eta above 600 GeV. More data is likely to confirm this unexpected edifice.

Title: A New Take on $\lambda$SUSY Inspired by the $\gamma\gamma$ Excess
Authors: P. Sanz, A. Hamada
Comments: 3 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

ATLAS and CMS have just presented an anomaly in run 2 at 1.9 sigma. Therefore, we consider the $\gamma\gamma$ anomaly in technicolor on AdS_5. Actually, the $X$ couples not only to $hh$, but also to $hh$. Assuming the $\gamma\gamma$ excess is real, we predict that new strong dynamics should be at 800 GeV. More data is likely to confirm this bewildering edifice.

Title: Interpretations of the 750 GeV Anomaly in Extensions of Composite Models
Comments: v4: 23 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this article, we address the recent diphoton excess at run 2 and the doublet-triplet splitting problem. Unsurprisingly, the $\gamma\gamma$ excess is analyzed in SO(10) with neutral fermions. Actually, the flavor symmetry protects the mass of the $\eta$. We predict a pion below 900 GeV. Finally, the phenomenology of SU(3)^3 is scrutinized and we derive anomalous dimensions.
