System-size dependence of charged-particle suppression in ultrarelativistic nucleus-nucleus collisions
High-energy partons lose energy while propagating through the hot, strongly interacting medium produced in ultrarelativistic nucleus-nucleus collisions, leading to a suppression of particle production at high transverse momentum ($ p_{\mathrm{T}} $). [...]

Observation of the jet diffusion wake using dijets in heavy ion collisions
Energetic quarks and gluons traversing a hot and dense quark-gluon plasma deposit energy and momentum into the medium before hadronizing to collimated sprays of particles, known as jets. [...]

Earth Matter Enhanced Axion Dark Matter Search / Huang, Xiaofei (Beihang U.) ; Ma, Xiaolin (QUP, Tsukuba ; KEK, Tsukuba ; Taiwan, Natl. Central U.) ; Xu, Zitong (Nanyang Technol. U.) ; Bloch, Itay M (CERN ; Technion) ; Wei, Kai (Beihang U. ; Sci. Tech. U., Beijing ; USTC, Hefei)
Laboratory searches for ultralight axion dark matter (DM) have traditionally assumed the terrestrial density of axions is equal to the average density of DM in the solar system. [...]

A multi-event interface for next-to-leading order calculations in MadGraph5_aMC@NLO / Frederix, Rikkert (Lund U. (main)) ; Roiser, Stefan (CERN) ; Schöfbeck, Robert (OAW, Vienna) ; Wettersten, Zenny (OAW, Vienna) ; Zaro, Marco (Milan U. ; INFN, Milan)
We detail the implementation of a multi-event interface for next-to-leading order (NLO) calculations in MadGraph5_aMC@NLO, allowing tree-level scattering amplitudes for multiple phase space points to be evaluated in each call to the integrated NLO differential cross section during event generation.
