    the underlying event in hard scattering collisions of proton and antiproton at tev by richard martin haas a dissertation presented to the graduate school of the university of florida in partial fulfillment of the requirements for the degree of doctor of philosophy university" of florida reproduced with permission of the copyright owner. A measurement of the underlying activity in scattering processes with p T scale in the GeV region is performed in proton–proton collisions at Ös = \sqrt{s} = TeV, using data collected by.

    The heaviest known particle, the top quark, has a mass equivalent to that of a gold atom or approximately times that of a proton. It is predominantly produced in pairs at the LHC, and the cross-section of top-quark pair production is expected to increase by a factor of at 13 TeV compared to the Run-1 8 TeV collisions. The authors study the behavior of the underlying event in hard scattering proton-antiproton collisions at TeV and compare with the QCD Monte-Carlo models. The underlying event is everything except the two outgoing hard scattered jets and receives contributions from the beam-beam remnants plus initial and final-state radiation.

The underlying event in hard scattering collisions of proton and antiproton at 1.8 TEV by Richard Martin Haas Download PDF EPUB FB2

Of course, from a certain point of view there is no such thing as an “underlying event" in a proton-antiproton collision. There is only an “event" and one cannot say where a given particle in the event originated. On the other hand, hard scattering collider “jet" events have a distinct topology.

Abstract: We study the behavior of the "underlying event" in hard scattering proton-antiproton collisions at TeV and compare with the QCD Monte-Carlo models.

Charged Jet Evolution and the Underlying Event in Proton-AntiProton Collisions at TeV Use the CDF “min-bias” data in conjunction with the CDF JET20 data to study the growth and development of “charged particle jets”.

The structure of events created from hard scattering pp¯ collisions at s = TeV is investigated. Among the various sources which produce observable features, the underlying event represents a poorly understood : R M Haas and R Field.

The underlying event in a hard scattering process has a “hard” component (particles that arise from initial & final-state radiation and from the outgoing hard scattered partons) and a “soft” component (beam-beam remnants).

In this thesis, studies of the underlying event in proton-proton colli-sions at a center-of-mass energy of p s= 10 TeV are presented. Crucial ingredient to underlying event models are multiple parton-parton scat-ters in single proton-proton collisions.

The feasibility of measuring the underlying event was investigated with the Compact Muon Solenoid.

We use the direction of the charged particle with the largest transverse momentum in each event to define three regions of η-ϕ space: “toward”, “away”, and “transverse.”.

soft collision with outgoing particles roughly in the same direction of the initial proton and antiproton, the so-called minimum bias event. Occasionally a hard 2-to-2 parton scattering happens, resulting in large transverse momentum jets whose direction remembers the 2-to-2 hard scattering subprocess, the two out-going partons (fig.
