Review of Particle Physics, 2016-2017
The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,283 new measurements from 899 papers, we list, evaluate, and average measured properties of
Tests of quantum gravity from observations of γ-ray bursts
The recent confirmation that at least some γ-ray bursts originate at cosmological distances suggests that the radiation from them could be used to probe some of the fundamental laws of physics. Here
Supersymmetric relics from the big bang
Abstract We consider the cosmological constraints on supersymmetric theories with a new, stable particle. Circumstantial evidence points to a neutral gauge/Higgs fermion as the best candidate for
Higgs Physics at the HL-LHC and HE-LHC
The discovery of the Higgs boson in 2012, by the ATLAS and CMS experiments, was a success achieved with only a percent of the entire dataset foreseen for the LHC. It opened a landscape of
Updated Nucleosynthesis Constraints on Unstable Relic Particles
We revisit the upper limits on the abundance of unstable massive relic particles provided by the success of Big-Bang Nucleosynthesis calculations. We use the cosmic microwave background data to
Flavour-Changing Decays of a 125 GeV Higgs-like Particle
Abstract The ATLAS and CMS experiments at the LHC have reported the observation of a possible excess of events corresponding to a new particle h with mass ∼125 GeV that might be the long-sought Higgs
Physics at the CLIC multi-TeV linear collider
This report summarizes a study of the physics potential of the CLIC e + e - linear collider operating at centre-of-mass energies from 1 TeV to 5 TeV with luminosity of the order of 10 35 cm -2 s -1 .
Geological Isotope Anomalies as Signatures of Nearby Supernovae
Nearby supernova explosions may cause geological isotope anomalies via the direct deposition of debris or by cosmic-ray spallation in the earth's atmosphere. We estimate the mass of material
Astrophysical Shrapnel: Discriminating among Near-Earth Stellar Explosion Sources of Live Radioactive Isotopes
We consider the production and deposition on Earth of isotopes with half-lives in the range 105-108 yr that might provide signatures of nearby stellar explosions, extending previous analyses of
