A global study of photon-induced jet production [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 2000
We present results of a global tuning of general purpose Monte Carlo models to published measurements of photon-proton -> jets at HERA and photon-photon -> jets at LEP and TRISTAN. The principle free parameters in the tuning are the simulation of the underlying event and the choice of photon structure. Several combinations of models are ruled out

Non-global logarithms in filtered jet algorithms [PDF]

open access: yesJournal of High Energy Physics, 2010
We analytically and numerically study the effect of perturbative gluons emission on the "Filtering analysis", which is part of a subjet analysis procedure proposed two years ago to possibly identify a low-mass Higgs boson decaying into b\bar{b} at the LHC.

Measurement of the top quark mass in the $$t\bar{t}\rightarrow $$ tt¯→ lepton+jets channel from $$\sqrt{s}=8$$ s=8  TeV ATLAS data and combination with previous results

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
The top quark mass is measured using a template method in the $$t\bar{t} \rightarrow \mathrm {lepton+jets}$$ tt¯→lepton+jets channel (lepton is e or $$\mu $$ μ ) using ATLAS data recorded in 2012 at the LHC.

NLL′ resummation of jet mass

open access: yesJournal of High Energy Physics, 2019
Starting from a factorization theorem in effective field theory, we present resummed results for two non-global observables: the invariant-mass distribution of jets and the energy distribution outside jets.

Global stability of a jet in crossflow [PDF]

open access: yesJournal of Fluid Mechanics, 2009
A linear stability analysis shows that the jet in crossflow is characterized by self-sustained global oscillations for a jet-to-crossflow velocity ratio of 3. A fully three-dimensional unstable steady-state solution and its associated global eigenmodes are computed by direct numerical simulations and iterative eigenvalue routines.

Hadronic calorimeter shower size: Challenges and opportunities for jet substructure in the superboosted regime

open access: yesPhysics Letters B, 2016
Hadrons have finite interaction size with dense material, a basic feature common to known forms of hadronic calorimeters (HCAL). We argue that substructure variables cannot use HCAL information to access the microscopic nature of jets much narrower than ...

Determination of jet calibration and energy resolution in proton–proton collisions at $$\sqrt{s} = 8~\hbox {TeV}$$ s = 8 TeV using the ATLAS detector

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
The jet energy scale, jet energy resolution, and their systematic uncertainties are measured for jets reconstructed with the ATLAS detector in 2012 using proton–proton data produced at a centre-of-mass energy of 8 TeV with an integrated luminosity of ...

Magnetosheath jet properties and evolution as determined by a global hybrid-Vlasov simulation [PDF]

open access: yesAnnales Geophysicae, 2018
We use a global hybrid-Vlasov simulation for the magnetosphere, Vlasiator, to investigate magnetosheath high-speed jets. Unlike many other hybrid-kinetic simulations, Vlasiator includes an unscaled geomagnetic dipole, indicating that the simulation ...

Forcing of globally unstable jets and flames

open access: green, 2012
In the analysis of thermoacoustic systems, a flame is usually characterised by the way its heat release responds to acoustic forcing. This response depends on the hydrodynamic stability of the flame. Some flames, such as a premixed bunsen flame, are hydrodynamically globally stable. They respond only at the forcing frequency.
