A Novel Approach to Reduce Derivative Costs in Variational Quantum Algorithms
Giovanni Minuto, Dario Melegari, Simone Caletti +1
We present a detailed numerical study of an alternative approach, named Quantum Non-Demolition Measurement (QNDM), to efficiently estimate the gradients or the Hessians of a quantu…
Flavoured jet algorithms: a comparative study
Arnd Behring, Simone Caletti, Francesco Giuli +17
The accurate identification of heavy-flavour jets, those which originate from bottom or charm quarks, is crucial for precision studies of the Standard Model and searches for new ph…
Tagging the initial state gluon in the Z+jet process
Simone Caletti
We develop a jet flavour tagger in the contest of electroweak boson production in association with jets. Here the jet with the highest transverse momentum is considered and a simpl…
Jet Angularities in Z+jet production at the LHC
Simone Caletti, Oleh Fedkevych, Simone Marzani +4
We present a phenomenological study of angularities measured on the highest transverse-momentum jet in LHC events that feature the associate production of a boson and one or mo…
On heavy-flavour jets with Soft Drop
Simone Caletti, Andrea Ghira, Simone Marzani
We study hadronic jets that are tagged as heavy-flavoured, i.e. they contain either beauty or charm. In particular, we consider heavy-flavour jets that have been groomed with the S…
Practical Jet Flavour Through NNLO
Simone Caletti, Andrew J. Larkoski, Simone Marzani +1
An infrared and collinear (IRC) safe definition of the partonic flavour of a jet is vital for precision predictions of quantum chromodynamics at colliders. Jet flavour definitions…
Quantum gradient evaluation through quantum non-demolition measurements
Paolo Solinas, Simone Caletti, Giovanni Minuto
We discuss a Quantum Non-Demolition Measurement (QNDM) protocol to estimate the derivatives of a cost function with a quantum computer. %This is a key step for the implementation o…
Tagging the initial-state gluon
Simone Caletti, Oleh Fedkevych, Simone Marzani +1
We study the production of an electroweak boson in association with jets, in processes where the jet with the highest transverse momentum is identified as quark-initiated. The quar…
Phenomenology of jet angularities at the LHC
Daniel Reichelt, Simone Caletti, Oleh Fedkevych +3
We compute resummed and matched predictions for jet angularities in hadronic dijet and Z+jet events with and without grooming the candidate jets using the SoftDrop technique. Our t…
NNLO QCD predictions for jet observables in ZH production at electron-positron colliders
Simone Caletti, Aude Gehrmann-De Ridder, Matteo Marcoli
We present precise predictions for a variety of jet observables in production at electron-positron colliders, with the boson decaying leptonically and the Higgs boson deca…
QCD predictions for vector boson plus hadron production at the LHC
Simone Caletti, Aude Gehrmann-De Ridder, Alexander Huss +2
The identification of a hadron in the final state of hadron-collider events that feature a leptonically decaying vector boson can provide essential information on the parton conten…
A Fragmentation Approach to Jet Flavor
Simone Caletti, Andrew J. Larkoski, Simone Marzani +1
An intuitive definition of the partonic flavor of a jet in quantum chromodynamics is often only well-defined in the deep ultraviolet, where the strong force becomes a free theory a…
