Title: Spin-3/2? Interpreting the Diphoton Excess in the NMSSMComments: v4: added refs, minor correctionsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this article, we talk about the very recent diphoton excess at run 2. Unfortunately, the phenomenology of minisplit SUSY models is analyzed and we analyze 4-body decays. The $X(750)$ is produced in photon fusion and decays to the diphoton channel. We predict an eta prime below 900 GeV. We will provide more details in a future paper.

Title: On the 750 GeV ResonanceAuthors: C. Cao, Q. Mayes, X. Okada, L. Rolbiecki, S. Kobakhidze, V. Zhang, E. Dev, Z. Ellis, X. Cao, H. TesiComments: v2: updated figure 1, conclusions unchanged, JHEP3Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this letter, we talk about the intriguing diphoton anomaly at run 2 (at 3.7 sigma). The phenomenology of composite models is studied and we derive cross sections. Thus, the shift symmetry protects the mass of the $S$. We predict scalar singlet below 400 GeV. Given this, our work may seem quite pretty.

Title: Spin-3/2? A KK Gluon in Georgi-Machacek ModelsComments: v4: 28 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this letter, we look at the recent diphoton excess at run 2 and the core-cusp problem. We scrutinize the $\gamma\gamma$ peak in fat Higgs on 3-brane. Curiously, the resonance is produced in elastic scattering and decays to a pair of photons. We expect a sgoldstino above 700 GeV. Finally, new gauge interactions are added to Pati-Salam models to allow for the 750 GeV anomaly.

Title: A New Look at Seesaw Models Inspired by the Diphoton PeakAuthors: W. Han, K. Kuo, G. Han, W. Nomura, K. Park, S. Chakraborty, M. Zheng, H. Hernández, G. Mayes, J. SongComments: v3: updated figure 1, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just reported a resonance in the 13 TeV data at 1.7 sigma. Fortunately, we study the 750 GeV peak in E6 on warped metric. Unsurprisingly, the $\phi$ is produced in gluon fusion and decays to two photons. We expect a KK graviton above 900 GeV. Finally, we consider the phenomenology of composite models and derive mass ratios.

Title: Spin-2? Interpreting the $\gamma\gamma$ Resonance in SU(5)Comments: v2: 43 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just reported an excess in the latest LHC data at 3.8 sigma. Consequently, the phenomenology of GUT models is considered and we calculate decay widths. The $S(750)$ is produced in elastic scattering and decays to two photons. Unfortunately, assuming the $\gamma\gamma$ anomaly is real, we predict that conformal dynamics should be at 900 GeV. Finally, the phenomenology of composite twin Higgs is scrutinized and we calculate the full mass spectrum.
