Higher-order hadronic vacuum polarization contribution to the muon $g-2$ from lattice QCD / Beltran, Arnau (U. Mainz, PRISMA) ; Conigli, Alessandro (Mainz U. ; Darmstadt, GSI) ; Kuberski, Simon (CERN) ; Meyer, Harvey B. (U. Mainz, PRISMA ; Mainz U. ; CERN) ; Ottnad, Konstantin (U. Mainz, PRISMA ; Bonn U., HISKP) ; Wittig, Hartmut (U. Mainz, PRISMA ; Mainz U. ; Darmstadt, GSI)
We present the first lattice QCD calculation of the next-to-leading order hadronic vacuum polarization contribution to the muon anomalous magnetic moment with sub-percent precision. [...]

On Thrust Resummation Ambiguities in $e^+e^-$ Annihilation into Hadrons / Buonocore, Luca (CERN) ; Nason, Paolo (INFN, Milan Bicocca) ; Rottoli, Luca (Milan Bicocca U. (main) ; INFN, Milan Bicocca) ; Torrielli, Paolo (INFN, Turin ; U. Turin (main))
In $e^+e^-$ shape-variable studies, and in particular for the case of thrust, fixed-order QCD predictions are typically supplemented with the resummation of contributions enhanced near the two-jet limit. [...]

Next-to-next-to-leading order event generation for $t\bar{t}H$ production with approximate two-loop amplitude / Biello, Christian (Zurich, ETH) ; Savoini, Chiara (Munich, Tech. U.) ; Signorile-Signorile, Chiara (CERN) ; Wiesemann, Marius (Garching, Max Planck Inst.)
We study Higgs-boson production in association with a top-quark pair ($t\bar{t}H$) at hadron colliders and present the first matching of next-to-next-to-leading order (NNLO) QCD corrections to parton showers using the MiNNLOPS method. [...]

(Mainz U. ; Helmholtz Inst., Mainz ; Darmstadt, GSI ; UC, Berkeley) ; Burrage, C. (Nottingham U.) et al.
Axions and other very weakly interacting slim particles (WISPs), with masses below 1 GeV, arise naturally in many extensions of the Standard Model of particle physics. [...]

Unshadowing the constituent quark number scaling of harmonic flow in heavy-ion collisions / Reichert, Tom (CERN ; Duke U.) ; Karpenko, Iurii (Prague, Tech. U.)
Constituent quark number scaling of elliptic flow has been proposed as one key observable to identify the phase transition or the absence of the Quark-Gluon Plasma (QGP) in heavy-ion collisions. [...]

A Matrix Theory Construction of the IIA/IIB Wall / Torres, Ethan (CERN)
In this note, we give a non-perturbative construction of a lightlike domain wall separating IIA and IIB string theories in 10D in the framework of discrete light-cone quantization (DLCQ). [...]

Fluctuations in atom interferometers as a new tool for dark matter / Murgui, Clara (CERN) ; Plestid, Ryan (CERN)

Acad. Hesse for FAIR)
We make predictions for the expected multiplicities of exotic charmed hadrons and charmed nuclei in Au+Au collisions at SIS100 and LHC beam energies, using input on light hadron and charm production from the UrQMD transport model, and applying the Thermal-FIST model. [...]
