Title: Tension With Run 1? Interpreting the Diphoton Excess in Twin HiggsComments: 2 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this letter, we look at the intriguing diphoton anomaly at run 2 and the diboson resonance. The phenomenology of minisplit SUSY models is analyzed and we derive correlations between $hh$ and $Z\gamma$. The $X$ is produced in elastic scattering and decays to a pair of photons. In short, we expect a pion above 500 GeV. We believe this is indicative of an ingenious principle.

Title: Interpretations of the $\gamma\gamma$ Anomaly in SU(5)Comments: 46 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just measured a resonance in run 2 of the LHC at 1.8 sigma. We analyze the phenomenology of the Fermi-Einstein model and compute production rates. The $S(750)$ is produced in photon fusion and decays to $\gamma\gamma$. Unfortunately, the $\gamma\gamma$ peak implies new gauge interactions around 500 GeV. We believe this is indicative of a perplexing truth.

Title: Tension With Run 1? Interpretations in SO(10)Comments: v4: 25 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this article, we talk about the recent diphoton excess at run 2 (at 1.1 sigma). The 750 GeV resonance is considered in composite models with exotic fermions. The $X(750)$ couples to $b\bar{b}$, but not to $Z\gamma$, worsening tension with Run 1. Curiously, the $S(750)$ couples to $WW$, but not to $ZZ$, alleviating tension with Run 1. We will provide more details in a future paper.

Title: A New Take on SU(3)^3 Inspired by the 750 GeV AnomalyAuthors: M. CaoComments: v3: 33 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this letter, we look at the very recent diphoton excess at run 2. The phenomenology of Seesaw models is scrutinized and we compute cross sections. The shift symmetry protects the mass of the $S$. Consequently, vector-like fermions at 600 GeV should be observed soon. Given this, our work may seem quite profound.

Title: The Diphoton Excess: Interpretations in the Broken MRSSMComments: 25 pages, 28 figuresSubjects: High Energy Physics - Phenomenology (hep-ph)
In this article, we discuss the intriguing diphoton peak at run 2 and $B \to D \tau \nu$. We study the $\gamma\gamma$ resonance in two Higgs doublet models. Unsurprisingly, a drawback of this model is that it explains $B \to D \tau \nu$. The diphoton peak implies conformal dynamics around 800 GeV. Actually, there is much to be done.
