In this paper, we look at the intriguing diphoton excess at run 2 and the core-cusp problem. Fortunately, although the $\gamma\gamma$ peak could be a statistical fluctuation, we scrutinize the phenomenology of the Bohr-Heisenberg model and derive cross sections. Remarkably, the $X(750)$ couples not only to $ZZ$, but also to $ZZ$. Assuming the diphoton resonance is real, we predict that heavy scalars should be at 900 GeV. Our results are similar to work done by Moroi and Zhu.

Title: On the Diphoton Excess
Authors: K. Cao
Comments: v2: 37 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just presented an anomaly in the 13 TeV data. Neutralinos are added to the broken MRSSM to account for the $\gamma\gamma$ resonance. Actually, the resonance couples not only to $ZZ$, but also to $Z\gamma$. Light axions at 700 GeV should be observed soon. Our results are similar to work done by Salvio.

Title: Interpretations of the 750 GeV Excess in Split SUSY Models
Comments: v4: 2 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

ATLAS and CMS have just observed an excess in the latest LHC data. Moreover, the diphoton peak is analyzed in the Einstein-Randall model with vector-like quarks. Unfortunately, the $S$ couples to $t\bar{t}$, but not to $Z\gamma$, removing tension with Run 1. The $\gamma\gamma$ resonance implies colored pions around 600 GeV. We leave the rest for future study.

Title: Interpretations of the Diphoton Peak in Little Higgs
Comments: v2: added refs
Subjects: High Energy Physics - Phenomenology (hep-ph)

Less than a year ago, ATLAS and CMS have measured a resonance in the second run of the LHC. Unfortunately, despite the fact that the diphoton excess could be a statistical fluctuation, we scrutinize the phenomenology of flipped SU(5) models and compute the full mass spectrum. Consequently, the $S$ couples not only to $ZZ$, but also to $b\bar{b}$. Vector-like quarks at 300 GeV should be observed soon. Our results are similar to work done by Buttazzo and Ibe.

Title: Interpretations of the 750 GeV Peak in Twin Higgs
Comments: v3: added refs
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just observed a resonance in run 2 at 3.6 sigma. Exotic fermions are added to folded SUSY to account for the 750 GeV anomaly. However, the $S(750)$ is produced in photon fusion and decays to $\gamma\gamma$. We predict an axion below 800 GeV. Given this, our work may seem quite detailed.
