Title: A New Take on Pati-Salam Models Inspired by the $\gamma\gamma$ AnomalyComments: 29 pages, 2 tablesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this article, we address the recent diphoton anomaly at run 2. Unsurprisingly, we analyze the phenomenology of the NMSSM and analyze anomalous dimensions. The $X$ couples not only to $t\bar{t}$, but also to $t\bar{t}$. Actually, we predict a sgoldstino below 600 GeV. We leave the rest for future study.

Title: A Common Framework for the 750 GeV Excess and the 2 TeV ResonanceComments: v4: added refs, no figures, based on a talk given on Polchinski's 20th birthdaySubjects: High Energy Physics - Phenomenology (hep-ph)
In this note, we address the intriguing diphoton anomaly at run 2 and $B \to D \tau \nu$. Fortunately, heavy scalars are added to SU(3)^3 to account for the $\gamma\gamma$ excess. Therefore, the $S(750)$ couples to $ZZ$, but not to $t\bar{t}$, worsening tension with Run 1. Assuming the 750 GeV peak is real, we predict that neutralinos should be at 800 GeV. Finally, we scrutinize the diphoton anomaly in little Higgs on a lattice.

Title: The $\gamma\gamma$ Resonance From Gauge-extended ModelsComments: 4 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this letter, we talk about the recent diphoton excess at run 2 (at 4.1 sigma). Unsurprisingly, despite the fact that the 750 GeV excess could be a statistical fluctuation, we study the phenomenology of composite models and calculate production rates. Quite simply, the discrete symmetry protects the mass of the $X(750)$. The $\gamma\gamma$ anomaly implies neutralinos around 600 GeV. Our results are similar to work done by Ren and Delaunay.

Title: Tension With Run 1? A Pseudo Nambu Goldstone Boson in Twin HiggsComments: 44 pages, 16 figuresSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just released an excess in run 2 of the LHC at 4.7 sigma. Surprisingly, we consider the 750 GeV excess in E6 with conformal dynamics. Unfortunately, the $S$ couples not only to $t\bar{t}$, but also to $b\bar{b}$. The $\gamma\gamma$ resonance implies neutralinos around 800 GeV. Our results are similar to work done by Vignaroli.

Title: On the Diphoton ExcessAuthors: B. FranceschiniComments: 18 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just seen an excess in the latest LHC data. We scrutinize the $\gamma\gamma$ anomaly in AdS/CFT. Therefore, the $S(750)$ couples to $Z\gamma$, but not to $Z\gamma$, decreasing tension with Run 1. We predict a pseudoscalar below 500 GeV. Finally, we analyze the phenomenology of split SUSY models and compute correlations between $t\bar{t}$ and $Z\gamma$.
