 Identification of boosted Higgs bosons decaying into $b$-quark pairs with the ATLAS detector at 13 TeV This paper describes a study of techniques for identifying Higgs bosons at high transverse momenta decaying into bottom-quark pairs, $H \rightarrow b\bar{b}$, for proton-proton collision data collected by the ATLAS detector at the Large Hadron Collider at a centre-of-mass energy $\sqrt{s}=13$ TeV.

 Unified No-Scale Attractors / Ellis, John ; Nanopoulos, Dimitri V. ; Olive, Keith A. ; Verner, Sarunas We have presented previously a general treatment of Starobinsky-like inflation in no-scale supergravity where the tensor-to-scalar ratio $r = 3(1 - n_s)^2$, and $n_s$ is the tilt of the scalar perturbations.

 Primordial black holes as dark matter candidate are severely constrained by the Galactic Center 511 keV gamma-ray line / Laha, Ranjan We derive the strongest constraint on the fraction of dark matter that can be composed of low mass primordial black holes by using the observation of the Galactic Center 511 keV gamma-ray line.
