Weak Corrections to Hadronic Observables
نویسنده
چکیده
We illustrate one-loop weak corrections to three-jet production in ee at √ s = MZ , to the production of a Z or γ in association with a hard jet at hadron colliders and to the production cross section of two b-jets at Tevatron and Large Hadron Collider (LHC).

Deeply Inelastic Hadronic Final States: QCD Corrections
The status of the calculation of next-to-leading-order QCD corrections to hadronic final states in deeply inelastic scattering is reviewed, and an overview of the phenomenology (including the measurement of the strong coupling constant and the gluon density via jet rates) is given. We also describe a new universal program (DISASTER++) for the calculation of (2+1)-jet observables.
متن کاملm b from the Hadronic Invariant Mass Moments of Semileptonic Inclusive B decay
We calculate the hadronic tensor for inclusive semileptonic B → Xc l ν̄ decay to O(αs). This allows O(αs ΛQCD/mb) corrections to hadronic invariant mass observables to be directly evaluated with experimentally required cuts on phase space. Several moments of phenomenological interest are presented to order O(αs ΛQCD/mb) and O (
متن کاملFRIF Workshop on First Principles Non-Perturbative QCD of Hadron Jets Power Corrections in Electron-Positron Annihilation: Experimental Review
Experimental studies of power corrections with ee data are reviewed. An overview of the available data for jet and event shape observables is given and recent analyses based on the Dokshitzer-Marchesini-Webber (DMW) model of power corrections are summarised. The studies involve both distributions of the observables and their mean values. The agreement between perturbative QCD combined with DMW ...

The program TOPAZ0 was developed for computing a variety of physical observables which are related to the e+e− annihilation into fermion pairs and to the large angle Bhabha scattering around the Z resonance. Among them, the Z parameters or pseudo-observables, the de-convoluted cross sections and those dressed with QED radiation, and finally the forward-backward asymmetries. The calculations are...
