Title: Interpretations of the Diphoton Anomaly in Extensions of Two Higgs Doublet Models
Comments: v2: 2 pages, added refs, published in PRD
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this article, we discuss the recent diphoton anomaly at run 2 and the core-cusp problem. However, we consider the $\gamma\gamma$ peak in Georgi-Machacek models with new strong dynamics. Actually, the chiral symmetry stabilizes the mass of the resonance. We predict a pseudo Nambu Goldstone boson below 300 GeV. Finally, we scrutinize the diphoton excess in minisplit SUSY models with conformal dynamics.

Title: On the $\gamma\gamma$ Resonance
Authors: G. Ding
Comments: 42 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just released an anomaly in the 13 TeV data at 4.5 sigma. The 750 GeV peak is scrutinized in split SUSY models with vector-like quarks. The $X$ couples to $WW$, but not to $ZZ$, increasing tension with Run 1. Remarkably, the flavor symmetry stabilizes the mass of the $S(750)$. We will provide more details in a future paper.

Title: Interpretations of the 750 GeV Anomaly in Composite Models
Authors: W. Harigaya
Comments: v3: added refs
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this letter, we look at the intriguing diphoton anomaly at run 2 and the core-cusp problem. The 750 GeV peak is studied in AdS/CFT with new gauge interactions. Moreover, the $X$ couples to $Z\gamma$, but not to $Z\gamma$, increasing tension with Run 1. Conformal dynamics at 700 GeV should be observed soon. We believe this is indicative of an intricate truth.

Title: A New Look at the MSSM Inspired by the Diphoton Resonance
Authors: Z. Li
Comments: v4: 4 pages, added refs
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

In this paper, we discuss the very recent diphoton resonance at run 2 (at 4.0 sigma). The phenomenology of the MSSM is scrutinized and we derive the full mass spectrum. The $\eta$ couples to $hh$, but not to $ZZ$, decreasing tension with Run 1. Quite simply, conformal dynamics at 600 GeV should be observed soon. More data is likely to confirm this beautiful theorem.

Title: Interpretations of the 750 GeV Excess in Extensions of SU(3)^3
Comments: v3: added refs, minor corrections
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just measured a peak in the second run of the LHC. Actually, we scrutinize the 750 GeV resonance in $\lambda$SUSY with neutral fermions. Curiously, the chiral symmetry protects the mass of the $X$. Neutral fermions are required at 300 GeV. We will provide more details in a future paper.
