Title: A New Take on Two Higgs Doublet Models Inspired by the 750 GeV PeakComments: v3: 3 pages, added refs, added refsSubjects: High Energy Physics  Phenomenology (hepph)
In this letter, we address the intriguing diphoton peak at run 2. Unsurprisingly, although the diphoton anomaly could be a statistical fluctuation, we study the diphoton excess in gaugeextended models with exotic fermions. The $S(750)$ couples not only to $Z\gamma$, but also to $hh$. Therefore, the $\gamma\gamma$ excess implies new gauge interactions around 700 GeV. Finally, we study the $\gamma\gamma$ anomaly in minimal composite Higgs on warped metric.

Title: On the $\gamma\gamma$ PeakComments: v4: updated figure 1, conclusions unchanged, published in PRD, based on a talk given on Fermi's 40th birthdaySubjects: High Energy Physics  Phenomenology (hepph); High Energy Physics  Theory (hepth)
In this note, we look at the recent diphoton anomaly at run 2. The diphoton resonance is studied in two Higgs doublet models with vectorlike quarks. Fortunately, a downside of this model is that $t\bar{t}$ and $ZZ$ are predicted to be large. We predict a dilaton below 700 GeV. More data should reveal the nature of the diphoton anomaly.

Title: A New Look at Composite Twin Higgs Inspired by the $\gamma\gamma$ PeakAuthors: S. FanComments: v4: updated figure 1, conclusions unchangedSubjects: High Energy Physics  Phenomenology (hepph); High Energy Physics  Theory (hepth)
ATLAS and CMS have just seen a peak in run 2 at 1.2 sigma. In short, the 750 GeV peak is scrutinized in PatiSalam models with vectorlike fermions. Interestingly, the discrete symmetry protects the mass of the $X(750)$, but not the Higgs. We predict a KK gluon below 400 GeV. We will provide more details in a future paper.

Title: A New Take on Technicolor Inspired by the $\gamma\gamma$ ExcessAuthors: I. WuComments: 38 pagesSubjects: High Energy Physics  Phenomenology (hepph); High Energy Physics  Experiment (hepex)
In this note, we talk about the recent diphoton anomaly at run 2 and the diboson resonance. We consider the diphoton excess in flipped SU(5) models. Actually, the shift symmetry stabilizes the mass of the $S(750)$. We expect an eta prime above 800 GeV. Finally, we consider the $\gamma\gamma$ peak in technicolor.

Title: Spin3/2? Calculating the One Loop Amplitude in Fat HiggsComments: 2 pagesSubjects: High Energy Physics  Phenomenology (hepph); High Energy Physics  Experiment (hepex)
ATLAS and CMS have just seen a peak in run 2 at 4.0 sigma. We consider the diphoton peak in the broken MRSSM. Surprisingly, a downside of this model is that it is very predictive. We expect a pseudoscalar above 600 GeV. We leave the rest for future study.
