Search for Higgs boson pair production in the $b\bar{b}WW^\ast$ decay mode at $\sqrt{s}=13$ TeV with the ATLAS detector
A search for Higgs boson pair production in the $b\bar{b}WW^\ast$ decay mode is performed in the $b\bar{b}l\nu qq$ final state using 36.1 fb$^{-1}$ of proton-proton collision data at a centre-of-mass energy of 13 TeV recorded with the ATLAS detector at the Large Hadron Collider. [...]

All-orders behaviour and renormalons in top-mass observables / Ferrario Ravasio, Silvia (INFN, Milan Bicocca ; Milan Bicocca U.) ; Nason, Paolo (CERN ; INFN, Milan Bicocca) ; Oleari, Carlo (INFN, Milan Bicocca ; Milan Bicocca U.)
We study a simplified model of top production and decay, consisting in a virtual vector boson $W^*$ decaying into a massive-massless $t$-$\bar{b}$ quark-antiquark pair. [...]

Optical trapping of anti-hydrogen towards an atomic anti-clock / Crivelli, P. (Zurich, ETH) ; Kolachevsky, N. (Lebedev Inst.)
The Anti-Matter Factory at CERN is gearing up, commissioning of the Extra Low ENergy Antiprotons (ELENA) ring is ongoing and the first anti-protons are foreseen to circulate in the decelerator very soon. [...]

$\mathcal{O}(a)$ improved quark mass renormalization for a non-perturbative matching of HQET to three-flavor QCD / Fritzsch, Patrick ; Heitger, Jochen ; Kuberski, Simon
The use of Heavy Quark Effective Theory (HQET) on the lattice as an approach to B-physics phenomenology is based on a non-perturbative matching of HQET to QCD in finite volume. [...]

Overview of recent femtoscopy measurements with ALICE / Janik, Małgorzata Anna
One of the key methods used in the study of the Quark-Gluon Plasma (QGP) is femtoscopy, the technique of measuring short-range two-particle correlations as a function of relative momentum. [...]

Serenity - An ATCA prototyping platform for CMS Phase-2 / Rose, Andrew (Imperial Coll., London) /CMS Collaboration
Serenity is an ATCA prototyping platform designed to explore alternative, novel design choices for CMS Phase-2. It uses a newly available interconnect technology from Samtec (Z-RAY) to mount a removable processing unit (FPGA) that should mitigate risk and provides significant flexibility in processing unit choice and connectivity.
