Luminosity-independent measurements of total, elastic and inelastic cross-sections at s = 7 TeV

Popis výsledku v původním jazyce

The TOTEM experiment at the LHC has performed the first luminosity-independent determination of the total proton-proton cross-section at $/sqrt{s} = 7$ TeV. This technique is based on the optical theorem and requires simultaneous measurements of the inelastic rate - accomplished with the forward charged-particle telescopes T1 and T2 in the range 3.1 <|?|<6.6 - and of the elastic rate by detecting the outcoming protons with Roman Pot detectors. The data presented here were collected in a dedicated run in2011 with special beam optics (?*=90 m) and Roman Pots approaching the beam close enough to register elastic events with squared four-momentum transfers |t| as low as 0.005 GeV**2. The luminosity-independent results for the elastic, inelastic and totalcross-sections are (25.1 $/pm$ 1.1) mb, (72.9 $/pm$ 1.5) mb and (98.0 $/pm$ 2.5), respectively.
