The role of multi-parton interactions in doubly-heavy hadron production Open
Beauty and charm quarks are ideal probes of pertubative Quantum Chromodymanics in proton–proton collisions, owing to their large masses. In this paper the role of multi-parton interactions in the production of doubly-heavy hadrons is studi…

A simple method to determine curvature biases in track reconstruction in hadron collider experiments Open
A new data-driven method, using $Z \rightarrow \mu^+ \mu^-$ decays, is proposed to correct for curvature biases in spectrometer experiments at hadron colliders. The method is studied assuming a detector with a forward-spectrometer geometry…

Simultaneously determining the $W^{\pm}$ boson mass and parton shower model parameters Open
We explore the possibility of simultaneously determining the $W$ boson mass, $m_{W}$, and QCD-related nuisance parameters that affect the $W$ boson $p_{\mathrm{T}}$ spectrum from a fit to the $p_{\mathrm{T}}$ spectrum of the muon in the le…

Understanding and constraining the PDF uncertainties in a $W$ boson mass measurement with LHCb Open
Precision electroweak tests are a powerful probe of physics beyond the Standard Model, but the sensitivity is limited by the precision with which the $W$ boson mass ($M_W$) has been measured. The Parton Distribution Function (PDF) uncertai…
