Stealth Supersymmetry Simplified

JiJi Fan, Rebecca Krall, David Pinner +2

In Stealth Supersymmetry, bounds on superpartners from direct searches can be notably weaker than in standard supersymmetric scenarios, due to suppressed missing energy. We present…

On the 750 GeV di-photon excess

Wolfgang Altmannshofer, Jamison Galloway, Stefania Gori +3

We explore several perturbative scenarios in which the di-photon excess at 750 GeV can potentially be explained: a scalar singlet, a two Higgs doublet model (2HDM), a 2HDM with an…

Evidence of sub-nucleonic degrees of freedom in J/ photoproduction in ultraperipheral collisions at the CERN Large Hadron Collider

E. Andrade-II, I. González, A. Deppman +1

We present calculations for the incoherent photoproduction of J/ vector mesons in ultra-peripheral heavy ion collisions (UPC) in terms of hadronic interactions. This study was c…

Heating up the Galaxy with Hidden Photons

Sergei Dubovsky, Guzmán Hernández-Chifflet

We elaborate on the dynamics of ionized interstellar medium in the presence of hidden photon dark matter. Our main focus is the ultra-light regime, where the hidden photon mass is…

Field Theory for Zero Sound and Ion Acoustic Wave in Astrophysical Matter

Gregory Gabadadze, Rachel A Rosen

We set up a field theory model to describe the longitudinal low energy modes in high density matter present in white dwarf stars. At the relevant scales, ions -- the nuclei of oxyg…

Multihadron production dynamics exploring the energy balance in hadronic and nuclear collisions

Edward K. G. Sarkisyan, Aditya Nath Mishra, Raghunath Sahoo +1

The multihadron production in nucleus-nucleus collisions and its interrelation with that in (anti)proton-proton interactions are studied by exploring the charged particle mean mult…
