/ATLAS ITK Collaboration
During the ATLAS phase II upgrade, the tracking system of the ATLAS experiment will be replaced by an all-silicon detector called the inner tracker (ITK) with a pixel detector as the most inner part. The monitoring data of the new system will be aggregated from an on-detector ASIC called Monitoring Of Pixel System (MOPS) and sent to the Detector Control System(DCS) using a new interface called MOPS-HUB.

How perturbative are heavy sea quarks?

/ALPHA Collaboration
Effects of heavy sea quarks on the low energy physics are described by an effective theory where the expansion parameter is the inverse quark mass, 1/$M$. At leading order in 1/$M$ (and neglecting light quark masses) the dependence of any low energy quantity on $M$ is given in terms of the ratio of $\Lambda$ parameters of the effective and the fundamental theory.

Hesse for FAIR) ; Bruno, Mattia (Milan Bicocca U. ; INFN, Milan Bicocca) ; Caselle, Michele (Turin U.) et al.
Phase transitions in a non-perturbative regime can be studied by ab initio Lattice Field Theory methods. The status and future research directions for LFT investigations of Quantum Chromo-Dynamics under extreme conditions are reviewed, including properties of hadrons and of the hypothesized QCD axion as inferred from QCD topology in different phases.

Hadronic vacuum polarization in the muon $g-2$: The short-distance contribution from lattice QCD
/ Kuberski, Simon (CERN) ; Cè, Marco (INFN, Milan Bicocca) ; von Hippel, Georg (U. Mainz, PRISMA) ; Meyer, Harvey B. (U. Mainz, PRISMA ; Mainz U., Inst. Phys. ; Darmstadt, GSI) ; Ottnad, Konstantin (U. Mainz, PRISMA) ; Risch, Andreas (Wuppertal U. ; NIC, Zeuthen ; DESY, Zeuthen) ; Wittig, Hartmut (U. Mainz, PRISMA ; Mainz U., Inst. Phys. ; Darmstadt, GSI)
We present results for the short-distance window observable of the hadronic vacuum polarization contribution to the muon $g-2$, computed via the time-momentum representation (TMR) in lattice QCD. A key novelty of our calculation is the reduction of discretization effects by a suitable subtraction applied to the TMR kernel function, which cancels the leading $x_0^4$-behaviour at short distances.

Amorphous carbon-coated storage cell tests for the polarized gas target at LHCb

The LHC beams cannot be polarized. Hence, the implementation of a dense polarized gas target at the LHCb experiment at CERN, to be operated simultaneously with beam–beam collisions, will enable high-energy fixed target interactions to explore a range of spin physics measurements. [...]

Heavy Wilson Quarks and O($a$) Improvement: Nonperturbative Results for $b_{\rm g}$
/ Dalla Brida, Mattia (CERN) ; Höllwieser, Roman (Wuppertal U.) ; Knechtli, Francesco (Wuppertal U.) ; Korzec, Tomasz (Wuppertal U.) ; Sint, Stefan (Hamilton Math. Inst., Dublin) ; Sommer, Rainer (Humboldt U., Berlin)
/ALPHA Collaboration
With Wilson quarks, on-shell O($a$) improvement of the lattice QCD action is achieved by including the Sheikholeslami-Wohlert term and two further operators of mass dimension 5, which amount to a mass-dependent rescaling of the bare parameters. We here focus on the rescaled bare coupling, $\tilde{g}_0^2 = g_0^2(1 + b_{\rm g} am_{\rm q})$, and the determination of $b_{\rm g}(g_0^2)$, which is currently only known to 1-loop order of perturbation theory.
