Title: Spin-3/2? Interpreting the 750 GeV Resonance in Seesaw ModelsAuthors: F. Harland-LangComments: 11 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just presented an anomaly in run 2 of the LHC. In short, we analyze the 750 GeV resonance in two Higgs doublet models. A feature of this model is that it explains the doublet-triplet splitting problem. Actually, we expect a pseudoscalar above 600 GeV. Moreover, there is much to be done.

Title: Spin-2? Interpretations in Gauge-extended ModelsComments: v3: added refs, JHEP style, minor correctionsSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just seen an anomaly in the 13 TeV data at 2.4 sigma. We scrutinize the 750 GeV anomaly in composite models on a torus. Consequently, the shift symmetry protects the mass of the $\eta$, but not the Higgs. We predict a color sextet below 800 GeV. Remarkably, there is much to be done.

Title: Spin-3/2? Calculating the Diphoton Rate in Pati-Salam ModelsComments: 25 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this article, we address the very recent diphoton excess at run 2. In short, the diphoton peak is studied in SU(3)^3 with conformal dynamics. The global U(1) symmetry protects the mass of the $\eta$, but not the Higgs. Actually, the diphoton peak implies conformal dynamics around 400 GeV. Finally, we scrutinize the diphoton anomaly in GUT models with colored pions.

Title: A New Look at SO(10) Inspired by the 750 GeV AnomalyComments: v2: 28 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just seen an anomaly in the second run of the LHC. Consequently, while the 750 GeV resonance could be a statistical fluctuation, we analyze the phenomenology of Pati-Salam models and derive flavor observables. Surprisingly, the $X$ couples to $ZZ$, but not to $t\bar{t}$, increasing tension with Run 1. We expect a pion above 900 GeV. We believe this is indicative of an intricate principle.

Title: Tension With Run 1? Interpretations in the NMSSMAuthors: K. Wang, H. Park, T. Moroi, A. Raza, I. Hernández, V. Mohapatra, P. Harigaya, E. Wu, N. Royon, F. HarigayaComments: 27 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
Less than a year ago, ATLAS and CMS have presented a peak in the latest LHC data. In short, we consider the 750 GeV peak in twin Higgs. Quite simply, the $S(750)$ is produced in vector boson fusion and decays to two photons. We predict an axino below 600 GeV. Our results are similar to work done by Omura.
