    The QCD sum rules approach is exposed in detail. A great variety of hadronic properties (masses of mesons and baryons, magnetic moments, form factors, quark distributions in hadrons, etc.) have been found using this method. The evolution of hadronic structure functions is presented in detail, together with polarization phenomena. Nov 19,  · T-odd correlations in top-quark pair production and decays (and references therein) can be investigated at the LHC: by using the momenta of the decay particles (or jets), asymmetries which probe CP can be formed, despite the CP asymmetry of the initial pp state, because the production mechanism is dominated by gluon or sea-studio.com: M S Sozzi.

    Measurement of event-by-event transverse momentum and multiplicity fluctuations the creation of the quark-gluon plasma (QGP) is expected. top SPS energy of A GeV. Evidence was found [6,7] that quark-gluon deconfinement sets in at a beam energy of about. A utility pole is a column or post used to support overhead power lines and various other public utilities, such as electrical cable, fiber optic cable, and related equipment such as transformers and street sea-studio.com can be referred to as a transmission pole, telephone pole, telecommunication pole, power pole, hydro pole, telegraph pole, or telegraph post, depending on its application.

    A search for charged Higgs bosons (\\PH±) decaying into a top and a bottom quark in the all-jet final states is presented. The analysis uses LHC proton-proton collision data recorded with the CMS detector in at √s=13\\TeV, corresponding to an integrated luminosity of \\fbinv. No significant excess is observed above the expected background. Model-independent upper limits at 95%. Run-1 ( Collision data) Vertex performance. The following plots are commented in document ATL-COM-PHYS They refer to data-taking, notice that plots for data are already available in the new vertex reconstruction plots page. The data are physics_MinBIas stream from period G4 (runs , , , , , , , , ), random .

The top quark is the heaviest currently known elementary particle. The only way the top quark can decay is through the weak interaction, which is the only interaction that allows quarks to change flavor (t → W + b).

Its large mass endows it with the largest so-called decay width, and hence. Abstract. The top quark is one of the third-generation quarks, proposed to exist in by Kobayashi and Maskawa to explain the observed CP violations in kaon decay [].However, it has not been directly observed until by CDF and DØ collaborations at the Tevatron [2, 3].The reason is that the top quark is the heaviest particle discovered so far, with a mass close to the electroweak Cited by: Measurement of the W Boson Mass with the D˜ Run II Detector using the Electron PT Spectrum A DISSERTATION The mass of the top quark versus the mass of the W boson.

We present a measurement of the transverse momentum distribution of dielectron pairs are taken from the Particle Data Book[. Note that the quark masses are ambiguous. This is due to the fact that all but the top quark are always bound in pairs and triplets.

Radial flow adds kinetic energy to the particle distribution and, therefore, modifies the spectra shapes. The new measurement, Spin correlations are suited to analyze in detail top quark interactions, search for new effects, and help to constrain the parton content of the proton.

The Higgs boson is an elementary particle in the Standard Model of particle physics, produced by the quantum excitation of the Higgs field, one of the fields in particle physics theory.

It is named after physicist Peter Higgs, who inalong with five other scientists, proposed the Higgs mechanism to explain why particles have mass. This mechanism implies the existence of the Higgs boson Mass: ± GeV/c².

The Higgs boson corresponds to the excess of events (blue) over the non-resonant ZZ* background (red) at GeV.

A rare Z boson decay into four leptons can also be observed at about 91 GeV.
