This paper describes a measurement of the $ Z/\gamma^* $ boson transverse momentum
spectrum using ATLAS proton-proton collision data at a centre-of-mass energy of $\sqrt {s} …

The reconstruction and calibration algorithms used to calculate missing transverse
momentum (E_ T^ miss ET miss) with the ATLAS detector exploit energy deposits in the …

The LHC (Large Hadron Collider) will serve as the energy frontier for high-energy physics
for the next 20 years. The highlight of the LHC running so far has been the discovery of the …

A bstract We carry out extensive tests of the next-to-leading logarithmic (NLL) accuracy of
the PanScales parton showers, as introduced recently for colour-singlet production in …

A bstract This paper describes a measurement of the Z/γ* boson transverse momentum
spectrum using ATLAS proton-proton collision data at a centre-of-mass energy of\(\sqrt {s} …

This letter reports the observation of photon-induced production of W-boson pairs, γ γ→ W
W. The analysis uses 139 fb− 1 of LHC proton–proton collision data taken at s= 13 TeV …

These lectures were given at TASI 2012 and are directed at a level suitable for graduate
students in High Energy Physics. They are intended to give an introduction to the theory and …

A bstract This article reports measurements characterizing the Underlying Event (UE)
associated with hard scatterings at midrapidity (| η|< 0. 8) in pp collisions at\(\sqrt {s}\)= 13 …

A bstract We present charged-particle distributions sensitive to the underlying event,
measured by the ATLAS detector in proton-proton collisions at a centre-of-mass energy of …

We define a new set of observables to probe the structure of the underlying event in hadron
collisions. We use the conventional definition of the “transverse region” in jet events and, for …
