high-pT jet at the LHC

چکیده
In the framework of the topcolor-assisted technicolor (TC2) model, we study production of the neutral top-pion π0 t in association with a high-pT jet at the LHC, which proceeds via the partonic processes gg −→ π0 t g, gq −→ π0 t q, qq̄ −→ π0 t g, gb(b̄) −→ π0 t b(b̄), and bb̄ −→ π0 t g. We find that it is very challenging to detect the neutral top-pion π0 t via the process pp −→ π0 t + jet +X → tt̄+ jet+X, while the possible signatures of π0 t might be detected via the process pp −→ π0 t + jet+X → (t̄c+ tc̄) + jet+X at the LHC. ∗E-mail:[email protected]

The production of SM Higgs bosons in hadron collisions at the LHC will proceed mainly via gluon fusion (gg → H). The detection of a SM Higgs boson with a mass below 140GeV at the LHC is rather difficult because the predominant decay into a bb̄-pair is swamped by the large QCD two-jet background . Therefore, only through observation of the rare decay into two photons, is the inclusive single Higg...

One of the important tools for studying the properties of quark-gluon plasma (QGP) in ultrarelativistic heavy ion collisions is the analysis of a QCD jet production. The medium-induced energy loss of energetic partons, “jet quenching”, should be very different in the cold nuclear matter and QGP, resulting in many observable phenomena . Recent RHIC data on high-pT particle production at √ s = 20...
متن کاملSimulation of jet quenching and high-pT particle production at RHIC and LHC
The model to simulate rescattering and partonic energy loss in ultrarelativistic heavy ion collisions is presented. The full heavy ion event is obtained as a superposition of a soft hydro-type state and hard multi-jets. This model is capable of reproducing main features of the jet quenching pattern at RHIC, and is applied to probe jet quenching in various novel channels at LHC.
متن کاملNeural Networks for calibrating ATLAS jets
The Large Hadron Collider (LHC) collides bunches of 10 protons at energies of 14 TeV every 25 ns. These parameters lead to an average of 40 collisions per bunch crossing, but most of them won’t correspond to head-on collisions, but rather a glancing collision, labeled as a pile-up (PU) event. Physicists at the LHC are interested in the high-energy or hard-scatter collision in a brunch crossing....
