Predictions for neutrinos and new physics from forward heavy hadron production at the LHC / Buonocore, Luca (Zurich U.) ; Kling, Felix (DESY) ; Rottoli, Luca (Zurich U.) ; Sominka, Jonas (Hamburg U.)
Scenarios with new physics particles feebly interacting with the Standard Model sector provide compelling candidates for dark matter searches. Geared with a set of new experiments for the detection of neutrinos and long-lived particles the Large Hadron Collider (LHC) has joined the hunt for these elusive states. [...]

Resummation of combined QCD-electroweak effects in Drell Yan lepton-pair production / Buonocore, Luca (CERN) ; Rottoli, Luca (Zurich U.) ; Torrielli, Paolo (Turin U.)
We consider neutral- and charged-current Drell Yan lepton-pair production at hadron colliders, and include dominant classes of electroweak and mixed QCD-electroweak corrections to all orders in perturbation theory. The accurate description of these physical effects is vital for a precise determination of fundamental Standard Model parameters, such as the $W$-boson mass and the electroweak mixing angle, as well as for a solid assessment of the associated theoretical uncertainties. [...]

Subleading power corrections for event shape variables in $e^+ e^-$ annihilation / Buonocore, Luca (Zurich U. ; CERN) ; Grazzini, Massimiliano (Zurich U.) ; Guadagni, Flavio (Zurich U.) ; Rottoli, Luca (Zurich U.)
We consider subleading power corrections to event shape variables in $e^+e^-$ collisions at the first order in the QCD coupling $\alpha_s$. We start from the jettiness variable $\tau_2$ and the $y_{23}$ resolution variable for the $k_T$ jet clustering algorithm and we analytically compute the corresponding cumulative cross section. [...]

Addendum to: Constraints on the quartic Higgs self-coupling from double-Higgs production at future hadron colliders [JHEP 10 (2019) 267] / Bizoń, Wojciech (Jagiellonian U.) ; Haisch, Ulrich (Munich, Max Planck Inst.) ; Rottoli, Luca (Zurich U.) ; Gillis, Zach (Chicago U. ; Chicago U., EFI) ; Moser, Brian (CERN) ; Windischhofer, Philipp (Chicago U. ; Chicago U., EFI ; Chicago U., Astron. Astrophys. Ctr. ; Chicago U., KICP)
We study inclusive double-Higgs boson production at the LHC and at the HL-LHC including variations of the trilinear and of the quartic Higgs boson self-couplings at next-to-leading order (NLO) in QCD with full top quark mass dependence. Our results include the two-loop contributions to the $gg \rightarrow HH$ amplitudes that involve a modified $h_4$ vertex calculated in arXiv:1810.04665. [...]

Exploring High-Purity Multiparton Scattering at Hadron Colliders / Andersen, Jeppe R. (Durham U.) ; Monni, Pier Francesco (CERN) ; Rottoli, Luca (Zurich U.) ; Salam, Gavin P. (Oxford U., Theor. Phys. ; Oxford U.) ; Soto-Ontoso, Alba (CERN)
Multi-parton interactions are a fascinating phenomenon that occur in almost every high-energy hadron--hadron collision, yet are remarkably difficult to study quantitatively. In this letter we present a strategy to optimally disentangle multi-parton interactions from the primary scattering in a collision. [...]

Quark and gluon two-loop beam functions for leading-jet $p_T$ and slicing at NNLO / Abreu, Samuel (CERN ; U. Edinburgh, Higgs Ctr. Theor. Phys.) ; Gaunt, Jonathan R. (Manchester U.) ; Monni, Pier Francesco (CERN) ; Rottoli, Luca (Zurich U.) ; Szafron, Robert (Brookhaven)
We compute the complete set of two-loop beam functions for the transverse momentum distribution of the leading jet produced in association with an arbitrary colour-singlet system. Our results constitute the last missing ingredient for the calculation of the jet-vetoed cross section at small veto scales at the next-to-next-to-leading order, as well as an important ingredient for its resummation to next-to-next-to-next-to-leading logarithmic order.

In these proceedings we study various sources of theoretical uncertainty in the Drell-Yan $p_T^{{\ell\ell}}$ spectrum focussing on the $p_T^{{\ell\ell}} \lesssim 100\, {\rm GeV}$ region. [...]
