Title: A New Take on $\lambda$SUSY Inspired by the Diphoton ResonanceAuthors: K. SantiagoComments: 25 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just reported an anomaly in run 2 of the LHC. The $\gamma\gamma$ excess is studied in E6 with vector-like quarks. The $\eta$ is produced in elastic scattering and decays to two photons. Surprisingly, the conformal symmetry protects the mass of the $X(750)$, but not the Higgs. Unsurprisingly, there is much to be done.

Title: The 750 GeV Excess From SU(5)Authors: X. NanopoulosComments: v2: added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
In this note, we address the very recent diphoton peak at run 2. We scrutinize the phenomenology of left-right models and analyze deviations to Higgs couplings. Curiously, a downside of this model is that $WW$ and $ZZ$ are predicted to be huge. The $\gamma\gamma$ anomaly implies heavy scalars around 900 GeV. Our results are similar to work done by Fan and Maxin.

Title: Tension With Run 1? Calculating the NLO Cross Section in the MSSMAuthors: E. HernándezComments: v4: added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just released an excess in the 13 TeV data. The phenomenology of Georgi-Machacek models is analyzed and we predict correlations between $WW$ and $b\bar{b}$. Curiously, the $S$ couples not only to $t\bar{t}$, but also to $ZZ$. We predict a pseudo Nambu Goldstone boson below 700 GeV. Given this, our work may seem quite beautiful.

Title: Interpretations of the Diphoton Peak in Extensions of Twin HiggsComments: v2: 3 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this note, we address the intriguing diphoton resonance at run 2 (at 4.2 sigma). The $\gamma\gamma$ peak is studied in singlet-extended models with vector-like fermions. Actually, a drawback of this model is that it cannot account for the strong CP problem. Assuming the $\gamma\gamma$ anomaly is real, we predict that neutral fermions should be at 500 GeV. Our results are similar to work done by Harland-Lang and Jiang.

Title: The Diphoton Peak From the Bohr-Heisenberg ModelComments: 2 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
A few months ago, ATLAS and CMS have observed a resonance in run 2 of the LHC. Consequently, we study the $\gamma\gamma$ resonance in GUT models with conformal dynamics. The discrete symmetry protects the mass of the $X$. We expect a KK graviton above 300 GeV. More data should reveal the nature of the 750 GeV resonance.
