Double diffractive cross-section measurement in the forward region at the LHC.
نویسندگان
چکیده
The first double diffractive cross-section measurement in the very forward region has been carried out by the TOTEM experiment at the LHC with a center-of-mass energy of sqrt[s]=7 TeV. By utilizing the very forward TOTEM tracking detectors T1 and T2, which extend up to |η|=6.5, a clean sample of double diffractive pp events was extracted. From these events, we determined the cross section σDD=(116±25) μb for events where both diffractive systems have 4.7<|η|min<6.5.

Physics with tagged forward protons at the LHC
We emphasize the importance of tagging the outgoing forward protons to sharpen the predictions for New Physics at the LHC (such as the diffractive production of a light Higgs boson). The rescattering effects lead to a rich distinctive structure of the cross section as a function of the transverse momenta of the protons. We show that a study of the correlations between the proton transverse mome...
متن کاملDouble Diffractive Higgs and Di-photon Production at the Tevatron and LHC
We use the POMWIG Monte Carlo generator to predict the cross-sections for double diffractive higgs and di-photon production at the Tevatron and LHC. We find that the higgs production cross-section is too small to be observable at Tevatron energies, and even at the LHC observation would be difficult. Double diffractive di-photon production, however, should be observable within one year of Tevatr...
متن کاملDiffractive Υ production at the Tevatron and LHC
We compute the rate for diffractive Υ meson production at the Tevatron and the LHC. The Υ is produced diffractively via the subprocess γ+p→ Υ+p where the initial photon is radiated off an incoming proton (or antiproton). We consider the possibility to use low angle proton detectors to make a measurement of the γp cross-section and conclude that a measurement of the cross-section at a centre of ...
متن کاملCMS results on soft diffraction
Diffractive interactions are characterized by the presence of at least one non-exponentially suppressed large rapidity gap (lrg) in the final state, defined as a region in pseudorapidity devoid of particles. The origin of lrgs is attributed to a color-singlet exchange with vacuum quantum numbers, referred to as Pomeron (IP ) exchange. Soft diffractive interactions (with no hard scale) cannot be...
متن کاملDiffractive Measurements in ATLAS
Measurements made using the ATLAS detector at the LHC at √ s = 7 TeV incorporating diffractive processes are presented. A first measurement of the inelastic cross-section using 20 μb−1 of data is given, yielding a result of σinel(ξ > 5 × 10−6) = 60.3 ± 2.1 mb, for single (pp→ X p) and double (pp→ XY ) diffractive processes for a kinematic range corresponding to detector acceptance ξ = MX/s calc...
