Les Houches Physics at TeV Colliders 2005, Standard Model and Higgs working group: Summary report
/ Buttar, C ; Dittmaier, S ; Drollinger, V ; Frixione, Stefano (INFN, Genoa) ; Nikitenko, A ; Abdullin, S W S ; Accomando, E ; Acosta, D ; Arbuzov, A ; Ball, R D et al.
This Report summarises the activities of the "SM and Higgs" working group for the Workshop "Physics at TeV Colliders", Les Houches, France, 2-20 May, 2005. On the one hand, we performed a variety of experimental and theoretical studies on standard candles (such as W, Z, and ttbar production), treating them either as proper signals of known physics, or as backgrounds to unknown physics; we also addressed issues relevant to those non-perturbative or semi-perturbative ingredients, such as Parton Density Functions and Underlying Events, whose understanding will be crucial for a proper simulation of the actual events taking place in the detectors.

Beam tests of ATLAS SCT silicon strip detector modules
/ Campabadal, F ; Fleta, C ; Key, M ; Lozano, M ; Martínez, C ; Pellegrini, G ; Rafí, J M ; Ullán, M ; Johansen, L ; Pommeresche, B et al.
The design and technology of the silicon strip detector modules for the Semiconductor Tracker (SCT) of the ATLAS experiment have been finalised in the last several years. Integral to this process has been the measurement and verification of the tracking performance of the different module types in test beams at the CERN SPS and the KEK PS. [...]

Using bin-by-bin corrections for track-based underlying event measurements in pp collisions at 900 GeV
/ Buckley, A; Chekanov, S; Hare, G; Kar, D; Moraes, A; Nielsen, J; Proudfoot, J; Yoshida, R; Wahrmund, S
Measurements of charged particle densities using minimum-bias events from proton-proton collisions at a center of mass energy of 900 GeV are presented. The densities and the average transverse momenta of charged particles are shown as a function of the transverse momenta of a leading in pT charged particle, concentrating on phase-space regions which are most sensitive to the underlying event.
