Does or did the supernova remnant Cassiopeia A operate as a PeVatron?
Zhen Cao, F. Aharonian, Q. An +276
For decades, supernova remnants (SNRs) have been considered the prime sources of Galactic Cosmic rays (CRs). But whether SNRs can accelerate CR protons to PeV energies and thus dom…
BSM Benchmarks for Effective Field Theories in Higgs and Electroweak Physics
D. Marzocca, F. Riva, J. Criado +9
Effective Field Theories (EFTs) capture effects from heavy dynamics at low energy and represent an essential ingredient in the context of Standard Model (SM) precision tests. This…
Les Houches 2013: Physics at TeV Colliders: New Physics Working Group Report
G. Brooijmans, R. Contino, B. Fuks +87
We present the activities of the "New Physics" working group for the "Physics at TeV Colliders" workshop (Les Houches, France, 3--21 June, 2013). Our report includes new computatio…
Search for Higgs Bosons and Other Massive States decaying into two Photons in e+e- Collisions at 189 GeV
The OPAL collaboration, G. Abbiendi et al
A search is described for the generic process e+e- to X Y, where X is a neutral heavy scalar boson decaying into a pair of photons, and Y is a neutral heavy boson (scalar or vector…
Search for Baryon and Lepton Number Violating Z0 Decays
