Title: A New Take on SU(5) Inspired by the Diphoton PeakAuthors: V. SantiagoComments: v2: 4 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just released an excess in the latest LHC data at 1.3 sigma. Light axions are added to folded SUSY to allow for the $\gamma\gamma$ anomaly. The R symmetry stabilizes the mass of the $X(750)$. However, assuming the 750 GeV excess is real, we predict that vector-like fermions should be at 500 GeV. Finally, neutralinos are added to singlet-extended models to account for the diphoton resonance.

Title: Tension With Run 1? An Axino in Pati-Salam ModelsComments: 24 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just observed an excess in run 2 of the LHC at 4.6 sigma. Vector-like fermions are added to left-right models to explain the 750 GeV peak. Fortunately, the $X$ is produced in vector boson fusion and decays to two photons. We expect a heavy pion above 900 GeV. We leave the rest for future study.

Title: Spin-2? A Sgoldstino in the MSSMAuthors: O. SadhukhanComments: 4 pages, pdflatex, no figuresSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
ATLAS and CMS have just observed a peak in the latest LHC data. Moreover, the diphoton anomaly is analyzed in little Higgs with light axions. The $S(750)$ is produced in photon fusion and decays to a pair of photons. Curiously, the diphoton anomaly implies exotic fermions around 900 GeV. We leave the rest for future study.

Title: The 750 GeV Anomaly as a Color SextetAuthors: J. UrbanoComments: v4: updated figure 3, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just measured a resonance in the 13 TeV data at 3.6 sigma. We analyze the phenomenology of Pati-Salam models and analyze mass ratios. The resonance couples not only to $hh$, but also to $b\bar{b}$. Remarkably, colored pions at 300 GeV should be observed soon. Given this, our work may seem quite elegant.

Title: Explaining the 750 GeV Excess and the Galactic Center ExcessComments: 13 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this article, we look at the recent diphoton excess at run 2. Curiously, despite the fact that the $\gamma\gamma$ resonance could be a statistical fluctuation, we scrutinize the phenomenology of technicolor and calculate decay widths. Fortunately, a drawback of this model is that it encapsulates all the relevant physics. Heavy scalars at 500 GeV should be observed soon. More data should reveal the nature of the 750 GeV excess.
