Phenomenology of single and double diffraction dissociation
Measurements at the lhc have shown that there are sizable disagreements among Monte Carlo (mc) implementations of “soft” processes based on cross sections proposed by various physics models, and that it is not possible to reliably predict all such processes, or even all aspects of a given process, using a single model [1, 2, 3]. In the cdf studies of diffraction at the Tevatron, all processes a...
متن کاملHigh mass diffraction at the LHC
We use a Monte Carlo implementation of recently developped models of exclusive diffractive W , top, Higgs and stop productions to assess the sensitivity of the LHC experiments. THEORETICAL FRAMEWORK The proposed model for pp → p+H + p, the Bialas-Landshoff (BL) [1] model, is based on a summation of two-gluon exchange Feynman graphs coupled to Higgs production by the top quark loop. The non-pert...
متن کاملDouble Diffraction Dissociation at High t
Diffractive scattering in the presence of a large momentum transfer is an ideal place to study the short distance rapidity gap producing mechanism. Previous studies (experimental and theoretical) in this area have focussed on gaps between jets and on high-t vector meson production. We propose the measurement of double dissociation at high-t. We examine the numerous advantages to studying this m...
متن کاملDouble diffraction dissociation at the Fermilab Tevatron collider.
We present results from a measurement of double diffraction dissociation in pp collisions at the Fermilab Tevatron collider. The production cross section for events with a central pseudorapidity gap of width Deltaeta(0)>3 (overlapping eta = 0) is found to be 4.43+/-0.02(stat)+/-1.18(syst) mb [ 3.42+/-0.01(stat)+/-1.09(syst) mb] at square root of (s) = 1800[630] GeV. Our results are compared wit...
متن کاملMultigap Diffraction at LHC
The large rapidity interval available at the Large Hadron Collider (LHC) offers an arena in which the QCD aspects of diffraction may be explored in an environment free of gap survival complications using events with multiple rapidity gaps. Presented at DIS-2005, XIIIth International Workshop on Deep Inelastic Scallering, April 27 May 1 2005, Madison, WI, U.S.A.
