This paper describes measurements of the sum of the transverse energy of particles as a function of particle pseudorapidity, ??, in proton-proton collisions at a centre-of-mass energy, TeX TeV using the ATLAS detector at the Large Hadron Collider. The measurements are performed in the region |??| < 4.8 for two event classes: those requiring the presence of particles with a low transverse momentum and those requiring particles with a significant transverse momentum. In the second dataset measurements are made in the region transverse to the hard scatter. The distributions are compared to the predictions of various Monte Carlo event generators, which generally tend to underestimate the amount of transverse energy at high |??|.

Abstract
This paper describes measurements of the sum of the transverse energy of particles as a function of particle pseudorapidity, ??, in proton-proton collisions at a centre-of-mass energy, TeX TeV using the ATLAS detector at the Large Hadron Collider. The measurements are performed in the region |??| < 4.8 for two event classes: those requiring the presence of particles with a low transverse momentum and those requiring particles with a significant transverse momentum. In the second dataset measurements are made in the region transverse to the hard scatter. The distributions are compared to the predictions of various Monte Carlo event generators, which generally tend to underestimate the amount of transverse energy at high |??|.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
