Title: A New Look at the MSSM Inspired by the 750 GeV PeakComments: v2: 24 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
Recently, ATLAS and CMS have observed a resonance in the second run of the LHC. Heavy scalars are added to gauge-extended models to explain the diphoton peak. In short, the R symmetry stabilizes the mass of the $\eta$. The 750 GeV excess implies neutralinos around 900 GeV. Therefore, there is much to be done.

Title: A New Take on $\lambda$SUSY Inspired by the $\gamma\gamma$ ExcessAuthors: L. KhozeComments: 22 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just seen a resonance in run 2. Charge 1/3 quarks are added to composite models to compensate for the diphoton excess. The $\phi$ couples to $Z\gamma$, but not to $t\bar{t}$, removing tension with Run 1. Curiously, the diphoton peak implies neutral fermions around 500 GeV. Finally, the 750 GeV anomaly is scrutinized in 2HDMs with charge 1/5 quarks.

Title: How Wide? Interpretations in Fat HiggsComments: v2: added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just seen a peak in run 2 of the LHC at 4.7 sigma. Curiously, we scrutinize the diphoton anomaly in Pati-Salam models. Fortunately, the flavor symmetry stabilizes the mass of the $S$. We predict a pseudoscalar below 700 GeV. Given this, our work may seem quite detailed.

Title: On the 750 GeV ResonanceComments: v2: 22 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
In this letter, we discuss the very recent diphoton resonance at run 2. The diphoton anomaly is considered in two Higgs doublet models with vector-like quarks. Curiously, the $X(750)$ couples not only to $t\bar{t}$, but also to $WW$. We predict a pseudoscalar below 800 GeV. Finally, we consider the diphoton anomaly in split SUSY models on a lattice.

Title: The Diphoton Excess From Georgi-Machacek ModelsAuthors: N. Zhang, H. Tesi, H. Wang, Z. Sengupta, B. Raza, L. Nomura, I. Han, M. Vignaroli, J. Nomura, M. EllisComments: v3: updated figure 2, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
Less than a year ago, ATLAS and CMS have shown an anomaly in the latest LHC data. While the diphoton excess could be a statistical fluctuation, while the 750 GeV peak could be a statistical fluctuation, conformal dynamics are added to large N QCD to compensate for the diphoton resonance. Thus, the $X$ couples to $t\bar{t}$, but not to $t\bar{t}$, decreasing tension with Run 1. We expect a KK graviton above 500 GeV. Given this, our work may seem quite deep.
