Analysis of high energy physics records in databases : science and technology indicators in high energy physics / Hillebrand, Claus-D (CERN)
An analysis of the literature on high energy physics was performed on the basis of the contents of the bibliographic database INIS (International Nuclear Information System). [...]

Studies of Boosted Topologies and Jet Substructure at the LHC / Haller, Johannes (Hamburg U.) ; Kogler, Roman (Hamburg U.) ; Tackmann, Frank (DESY)
The high centre-of mass energy available in run-2 of CERN's Large-Hadron-Collider (LHC) results in an abundant production of heavy particles with high transverse momenta ($p_T$). [...]

Searching for hidden matter with long-range angular correlations at $e^+e^-$ colliders / Pérez-Ramos, Redamy (IPSA, Paris) ; Sanchis-Lozano, Miguel-Angel (Valencia U., IFIC ; Valencia U.) ; Sarkisyan-Grinbaum, Edward K. (CERN ; Texas U., Arlington)
The analysis of azimuthal correlations in multiparticle production can be useful to uncover the existence of new physics beyond the Standard Model, e.g., Hidden Valley, in $e^+e^-$ annihilation at high energies. [...]

R-Parity Violation Axiogenesis / Co, Raymond T. (Minnesota U., Theor. Phys. Inst.) ; Harigaya, Keisuke (CERN ; Princeton, Inst. Advanced Study) ; Johnson, Zachary ; Pierce, Aaron
We show that the rotation of the QCD axion field, aided by $B-L$ violation from supersymmetric $R$-parity violating couplings, can yield the observed baryon abundance. [...]

Jet substructure measurements in heavy-ion collisions with ALICE / Mulligan, James (Ahmedabad, Phys. Res. Lab ; Indian Inst. Tech., Gandhinagar)
Jet substructure, defined by observables constructed from the distribution of constituents within a jet, provides the versatility to tailor observables to specific regions of QCD radiation phase space. [...]

Measurements of inclusive photons at forward rapidities in p-Pb collisions at $\sqrt{s\rm_{NN}}$ = 5.02 TeV with ALICE / Modak, Abhi (Lund U.)
We present multiplicity and pseudorapidity distributions of inclusive photons at forward rapidity in proton-lead (p-Pb) collisions at $\sqrt{s\rm_{NN}}$ = 5.02 TeV using the data obtained from Photon Multiplicity Detector (PMD) of ALICE. [...]

First search for exclusive diphoton production at high mass with tagged protons in proton-proton collisions at $\sqrt{s} = $ 13 TeV / CMS Collaboration
A search for exclusive two-photon production via photon exchange in proton-proton collisions, ${\mathrm{p}}{\mathrm{p}}\to{\mathrm{p}}\gamma\gamma{\mathrm{p}}$ with intact protons, is presented. [...]

Observation of two new excited ${\it\Xi}_b^0$ states decaying to ${\it\Lambda}_b^0 K^-\pi^+$ / LHCb Collaboration
Two narrow resonant states are observed in the ${\it\Lambda}_b^0 K^-\pi^+$ mass spectrum using a data sample of proton-proton collisions at a center-of-mass energy of 13$\rm TeV$, collected by the LHCb experiment and corresponding to an integrated luminosity of $6~{\rm fb}^{-1}$. [...]
