A Theory of Dark Pions / Cheng, Hsin-Chia ; Li, Lingfeng ; Salvioni, Ennio
We present a complete model of a dark QCD sector with light dark pions, broadly motivated by hidden naturalness arguments. [...]

Axion Homeopathy: Screening Dilaton Interactions / Burgess, C.P. (McMaster U. ; Perimeter Inst. Theor. Phys. ; CERN) ; Quevedo, F.
Cosmologically active Brans-Dicke (or dilaton) scalar fields are generically ruled out by solar system tests of gravity unless their couplings to ordinary matter are much suppressed relative to gravitational strength, and this is a major hindrance when building realistic models of light dilatons coupled to matter. [...]

Dark Matter Freeze-In with a Heavy Mediator: Beyond the EFT Approach / Frangipane, Evan (UC, Santa Cruz) ; Gori, Stefania (UC, Santa Cruz) ; Shakya, Bibhushan (DESY ; CERN)
We study dark matter freeze-in scenarios where the mass of the mediator particle that couples dark matter to the Standard Model is larger than the reheat temperature, TRH, in the early Universe. [...]

BLEMAB European project: muon imaging technique applied to blast furnaces / BLEMAB Collaboration
The BLEMAB European project (BLast furnace stack density Estimation through on-line Muon ABsorption measurements), evolution of the previous Mu-Blast European project, is designed to investigate in detail the capability of muon radiography techniques applied to the imaging of a blast furnace's inner zone. [...]

Sci. Dept.) ; Nishimichi, Takahiro (Kyoto U., Yukawa Inst., Kyoto ; Tokyo U., IPMU) ; Simonović, Marko (CERN) ; Takada, Masahiro (Tokyo U., IPMU) ; Zaldarriaga, Matias (Princeton, Inst. Advanced Study)
We study the information content of the angle-averaged (monopole) redshift space galaxy bispectrum. [...]

A Neural-Network-defined Gaussian Mixture Model for particle identification applied to the LHCb fixed-target programme / Graziani, Giacomo (INFN, Florence) ; Anderlini, Lucio (INFN, Florence) ; Mariani, Saverio (INFN, Florence ; Florence U. ; CERN) ; Franzoso, Edoardo (INFN, Ferrara ; Ferrara U.) ; Pappalardo, Luciano (INFN, Ferrara ; Ferrara U.) ; di Nezza, Pasquale (Frascati)
Particle identification in large high-energy physics experiments typically relies on classifiers obtained by combining many experimental observables. [...]

Combined-function optics for circular high-energy hadron colliders / Giovannozzi, M. (CERN) ; Todesco, E. (CERN)
The design of future circular high-energy hadron colliders is based on the achievement of challenging magnetic fields, needed to keep the hadron beams orbiting along the ring circumference. [...]

Measurement of the inclusive and differential WZ production cross sections, polarization angles, and triple gauge couplings in pp collisions at $\sqrt{s} = $ 13 TeV / CMS Collaboration
The associated production of a W and a Z boson is studied in final states with multiple leptons produced in proton-proton (pp) collisions at a centre-of-mass energy of 13 TeV using 137 fb$^{-1}$ of data collected with the CMS detector at the LHC. [...]

Recent results of $\text{D}^{0}$ mesons azimuthal anisotropy using the CMS detector / Bernardes, Cesar A. (Madrid U. ; Frankfurt U.)
In a relativistic heavy ion collision, heavy flavor (charm and bottom) quarks are mostly created via hard processes at the early stage of the collisions. [...]
