Triggering Soft Bombs at the LHC
Simon Knapen, Simone Pagan Griso, Michele Papucci +1
Very high multiplicity, spherically-symmetric distributions of soft particles, with ~ few hundred MeV, may be a signature of strongly-coupled hidden valleys that exhibit long…
New Physics in the Visible Final States of
Zoltan Ligeti, Michele Papucci, Dean J. Robinson
We derive compact expressions for the helicity amplitudes of the many-body decays, specifically for or and or . We inc…
Diphotons from an Electroweak Triplet-Singlet
Kiel Howe, Simon Knapen, Dean J. Robinson
The neutral component of a real pseudoscalar electroweak (EW) triplet can produce a diphoton excess at 750 GeV, if it is somewhat mixed with an EW singlet pseudoscalar. This triple…
A White Paper on keV Sterile Neutrino Dark Matter
R. Adhikari, M. Agostini, N. Anh Ky +133
We present a comprehensive review of keV-scale sterile neutrino Dark Matter, collecting views and insights from all disciplines involved - cosmology, astrophysics, nuclear, and par…
Gamma-rays from Dark Showers with Twin Higgs Models
Marat Freytsis, Simon Knapen, Dean J. Robinson +1
We consider a twin WIMP scenario whose twin sector contains a full dark copy of the SM hadrons, where the lightest twin particles are twin pions. By analogy to the standard WIMP pa…
