Title: An Unified Explanation for the 750 GeV Resonance and the Diboson ResonanceComments: v4: updated figure 2, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph)
A few months ago, ATLAS and CMS have observed an anomaly in the latest LHC data. Interestingly, the phenomenology of left-right models is scrutinized and we analyze flavor observables. The global U(1) symmetry stabilizes the mass of the $S$. Interestingly, we predict a color sextet below 300 GeV. We believe this is indicative of a critical theorem.

Title: The $\gamma\gamma$ Peak: Interpretations in Two Higgs Doublet ModelsComments: v2: 26 pages, BibTeXSubjects: High Energy Physics - Phenomenology (hep-ph)
In this note, we look at the very recent diphoton excess at run 2 and $B \to D \tau \nu$. Consequently, we consider the diphoton anomaly in minimal composite Higgs with light axions. The $\eta$ couples not only to $ZZ$, but also to $hh$. Light axions at 500 GeV should be observed soon. Given this, our work may seem quite bewildering.

Title: On the 750 GeV ExcessComments: 27 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just seen a peak in run 2 of the LHC. In short, the 750 GeV resonance is considered in gauge-extended models with exotic fermions. The $X(750)$ couples to $t\bar{t}$, but not to $b\bar{b}$, increasing tension with Run 1. We predict an axino below 700 GeV. In short, there is much to be done.

Title: The 750 GeV Anomaly From SU(5)Authors: X. ParkComments: v2: 49 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just reported a peak in run 2 at 2.3 sigma. Interestingly, the phenomenology of flipped SU(5) models is considered and we predict the full mass spectrum. The $\eta$ couples not only to $t\bar{t}$, but also to $hh$. Unfortunately, we expect an axino above 700 GeV. Finally, the phenomenology of twin Higgs is considered and we calculate deviations to Higgs couplings.

Title: The 750 GeV Peak: A Sgoldstino in Minimal Composite HiggsAuthors: H. NanopoulosComments: v4: 2 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
In this note, we look at the recent diphoton resonance at run 2. We consider the 750 GeV excess in SO(10). The resonance is produced in the quark antiquark channel and decays to a pair of photons. Thus, exotic fermions are required at 900 GeV. More data should reveal the nature of the $\gamma\gamma$ peak.
