Title: Relating the 750 GeV Resonance and Muon g-2Comments: v4: 3 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just released an excess in run 2 at 2.8 sigma. Unsurprisingly, we scrutinize the phenomenology of Seesaw models and analyze production rates. The $X$ couples not only to $ZZ$, but also to $WW$. Light axions at 700 GeV should be observed soon. Our results are similar to work done by Li and Cline.

Title: The 750 GeV Resonance: Interpreting the Diphoton Anomaly in Flipped SU(5) ModelsComments: 13 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
ATLAS and CMS have just presented a resonance in the 13 TeV data. We scrutinize the phenomenology of $\lambda$SUSY and compute decay widths. A feature of this model is that it cannot account for the 2 TeV resonance. Moreover, the $S(750)$ couples not only to $ZZ$, but also to $t\bar{t}$. We will provide more details in a future paper.

Title: The 750 GeV Peak as a Pseudo Nambu Goldstone BosonComments: v4: 4 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this letter, we discuss the very recent diphoton peak at run 2 (at 3.0 sigma). Vector-like fermions are added to the Georgi-Georgi model to explain the $\gamma\gamma$ resonance. Unfortunately, the discrete symmetry protects the mass of the $X$, but not the Higgs. Light axions at 800 GeV should be observed soon. Unfortunately, there is much to be done.

Title: On the Diphoton AnomalyComments: v4: 40 pages, added refs, no figuresSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this article, we talk about the very recent diphoton anomaly at run 2 and $h \to \mu \tau$. Colored pions are added to composite models to allow for the $\gamma\gamma$ excess. Curiously, the $S$ couples to $Z\gamma$, but not to $WW$, increasing tension with Run 1. Heavy scalars at 500 GeV should be observed soon. Given this, our work may seem quite bewildering.

Title: On the Diphoton ExcessComments: v4: 3 pages, added refs, 45 figuresSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this note, we look at the very recent diphoton resonance at run 2 (at 2.8 sigma). Fortunately, the phenomenology of the broken MRSSM is studied and we compute cross sections. Unfortunately, the $\phi$ is produced in the quark antiquark channel and decays to two photons. Assuming the 750 GeV anomaly is real, we predict that heavy scalars should be at 600 GeV. Our results are similar to work done by Arun and Han.
