QUANTUM COMPUTING
Quantum machine learning for particle track reconstruction (arXiv:2212.07279)
This paper presents a hyrbid classical-quantum machine learning algorithm towards reconstructing particle trajectories at the High Luminosity Large Hadron Collider. It proposes a classical support vector machine (SVM) with a quantum-estimated kernel and uses this to classify a set of three hits (triplets) as either belonging to or not belonging to the same particle track.
A quantum walk approach to parton showers (arxiv:2109.13975)
This paper presents a novel quantum walk approach to simulating parton showers on a quantum computer. We demonstrate that the quantum walk paradigm offers a natural and more efficient approach to simulating parton showers on quantum devices, significantly increasing the number of steps of the parton shower that can be simulated compared to previous quantum algorithms.
Towards a Quantum Computing Algorithm for Helicity Amplitudes and Parton Showers (arxiv:2010.00046)
This paper proposes general and extendable algorithms for quantum gate computers to facilitate calculations of helicity amplitudes and the parton shower process. The helicity amplitude calculation exploits the equivalence between spinors and qubits and the unique features of a quantum computer to compute the helicities of each particle involved simultaneously, thus fully utilising the quantum nature of the computation. The parton shower algorithm simulates collinear emission for a two-step, discrete parton shower.
PRECISION PHYSICS
Precision measurement of the Z boson invisible width at the CMS experiment (CMS-PAS-SMP-18-014)
This result is the first measurement of the Z invisible width at a hadron collider and is the single most precise direct measurement in the world, competitive with the combined direct measurement from the LEP experiments. The invisible width is measured to be 523±3(stat)±16(syst) MeV.

Measurement of Z/γ ratio and collinear Z emission at the CMS experiment (arXiv:2102.02238)
This result presents the first measurement of the ratio of the differential cross sections of Z + jets and γ + jets production at 13 TeV of LHC, as well as the first direct measurement of Z bosons emitted collinearly with a jet at the LHC.
Measurement of the W Boson Width in proton-antiproton collisions at the Tevatron, CDF collaboration, Phys. Rev. Lett. 100, 071801 (2008)
This measurement is the most precise direct measurement of the W boson width. The result is ΓW = 2032 ± 45(stat) ± 57(syst) MeV, consistent with the standard model expectation.
Precision Measurement of the W-Boson Mass with the CDF II Detector, CDF Collaboration, Phys. Rev. Lett. 108, 151803 (2012)
This is the most precise measurement of the W-boson mass to date and significantly exceeds the precision of all previous measurements combined. The measured value is 80 387±19 MeV.
