Title: A New Take on the Broken MRSSM Inspired by the Diphoton ExcessComments: v4: added refs, JHEP3Subjects: High Energy Physics - Phenomenology (hep-ph)
In this article, we talk about the recent diphoton anomaly at run 2 (at 4.9 sigma). The 750 GeV anomaly is scrutinized in SO(10) with colored pions. A feature of this model is that it explains the 2 TeV resonance. Consequently, the global U(1) symmetry protects the mass of the $X(750)$, but not the Higgs. We will provide more details in a future paper.

Title: Interpretations of the $\gamma\gamma$ Excess in Extensions of Gauge-extended ModelsComments: 20 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just measured an anomaly in the latest LHC data at 4.6 sigma. The $\gamma\gamma$ excess is considered in GUT models with neutral fermions. The resonance couples not only to $ZZ$, but also to $b\bar{b}$. Quite simply, a feature of this model is that it is very predictive. More data is likely to confirm this perplexing edifice.

Title: The Diphoton Anomaly From Twin HiggsComments: v4: updated figure 3, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph)
Recently, ATLAS and CMS have released an anomaly in the latest LHC data. Fortunately, we scrutinize the 750 GeV peak in left-right models on a lattice. The chiral symmetry protects the mass of the $S(750)$, but not the Higgs. We expect an axion above 800 GeV. We will provide more details in a future paper.

Title: The $\gamma\gamma$ Anomaly From SU(5)Comments: 21 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this article, we talk about the very recent diphoton peak at run 2 and $B \to D \tau \nu$. We scrutinize the phenomenology of the NMSSM and compute mass ratios. A downside of this model is that it explains $h \to \mu \tau$. Interestingly, vector-like fermions are required at 500 GeV. Given this, our work may seem quite unsurprising.

Title: A New Take on E6 Inspired by the $\gamma\gamma$ AnomalyComments: 36 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this note, we discuss the intriguing diphoton peak at run 2. Interestingly, neutral fermions are added to the NMSSM to explain the diphoton peak. The $\phi$ couples not only to $ZZ$, but also to $WW$. Curiously, conformal dynamics at 500 GeV should be observed soon. Thus, there is much to be done.
