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. [...]

J/$\psi$ production as a function of charged-particle multiplicity in pp collisions at $\sqrt{s}$ = 5.02 TeV with ALICE / Khatun, Anisa
The relative J/$\psi$ yields as a function of relative charged-particle multiplicity in pp collisions at $\sqrt{s}$ = 5.02 TeV, measured at forward rapidity, are investigated for the first time. [...]

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. [...]

Searching for muonic forces with the ATLAS detector / Galon, Iftah ; Kajamovitz, Enrique ; Shih, David ; Soreq, Yotam ; Tarem, Shlomit
The LHC copiously produces muons via different processes, and the muon sample will be large at the high-luminosity LHC (HL-LHC). [...]

Real-time discrimination of photon pairs using machine learning at the LHC / Benson, Sean ; Casais Vidal, Adrián ; Cid Vidal, Xabier ; Puig Navarro, Albert
ALPs and other as-yet unobserved $B$ decays to di-photon final states are a challenge to select in hadron collider environments due to the large backgrounds that come directly from the $pp$ collision. [...]
