1. Dedicated strategies for triboson signals from cascade decays of vector resonances / Agashe, Kaustubh ; Collins, Jack H. ; Du, Peizhi ; Hong, Sungwoo ; et al
New colorless electroweak (EW) charged spin-1 particles with mass of a few TeV arise in numerous extensions of the standard model (SM). [...]

2. Natural seesaw and leptogenesis from hybrid of high-scale type I and TeV-scale inverse / Agashe, Kaustubh ; Du, Peizhi ; Ekhterachian, Majid ; Fong, Chee ; et al
We develop an extension of the basic inverse seesaw model which addresses simultaneously two of its drawbacks, namely, the lack of explanation of the tiny Majorana mass term μ for the TeV-scale singlet fermions and the difficulty in achieving successful leptogenesis. [...]

3. Detecting a boosted diboson resonance / Agashe, Kaustubh ; Collins, Jack ; Du, Peizhi ; Hong, Sungwoo ; et al
New light scalar particles in the mass range of hundreds of GeV, decaying into a pair of W / Z bosons can appear in several extensions of the SM. [...]

4. Hybrid seesaw leptogenesis and TeV singlets / Agashe, Kaustubh ; Du, Peizhi ; Ekhterachian, Majid ; Fong, Chee Sheng ; et al
The appealing feature of inverse seesaw models is that the Standard Model (SM) neutrino mass emerges from the exchange of TeV scale singlets with sizable Yukawa couplings, which can be tested at colliders. [...]

6. LHC signals for singlet neutrinos from a natural warped seesaw mechanism. II / Agashe, Kaustubh ; Du, Peizhi ; Hong, Sungwoo
A natural seesaw mechanism for obtaining the observed size of SM neutrino masses can arise in a warped extra-dimensional/composite Higgs framework. [...]

7. LHC signals from cascade decays of warped vector resonances / Agashe, Kaustubh ; Collins, Jack ; Du, Peizhi ; Hong, Sungwoo ; et al
Recently (arXiv:1608.00526), a new framework for warped higher-dimensional compactifications with “bulk” standard model (SM) was proposed: in addition to the UV (Planck scale) and IR (a couple of TeV) branes, there is an intermediate brane, taken to be around 10TeV. [...]

8. Flavor universal resonances and warped gravity / Agashe, Kaustubh ; Du, Peizhi ; Hong, Sungwoo ; Sundrum, Raman
Warped higher-dimensional compactifications with “bulk” standard model, or their AdS/CFT dual as the purely 4D scenario of Higgs compositeness and partial compositeness, offer an elegant approach to resolving the electroweak hierarchy problem as well as the origins of flavor structure. [...]

9. Permutation relations of generalized Yangian Invariants, unitarity cuts, and scattering amplitudes / Peizhi Du ; Gang Chen ; Yeuk-Kwan E. Cheung
We find a permutation relation among the generalized Yangian Invariants — two Yangian Invariants with adjacent external lines exchanged are related by a simple kinematic factor — which is shown to be equivalent to U(1) decoupling and Bern-Carrasco-Johansson (BCJ) relation at the level of maximal helicity violating (MHV) amplitudes.
