Measurement of the Inclusive Z+Jet(s) Production Cross Section at CDF
We present preliminary results on inclusive Z(→ ee) boson plus jets production in p p ¯ collisions at s = 1.96 TeV , based on 1 fb −1 of data collected by the CDF experiment between February 2002 and March 2006. Inclusive jet measurements are performed as a function of p T jet and jet multiplicity for jets in the region p T jet > 30 GeV/c and | y jet | 2.1 . Results are compared to NLO pQCD predictions.

Search for new phenomena in events with a monojet and large missing transverse momentum at the LHC using the ATLAS detector
We report preliminary results on a search for new phenomena in an event sample with monojets and large missing transverse momentum in the final state. The analysis uses 1.00 fb−1 of data collected in 2011 with the ATLAS detector [1]. Good agreement is observed between the number of events in data and the Standard Model predictions. The results are translated into improved limits on a model with Large Extra Dimensions.

Z plus jets production at the tevatron
We present preliminary results on inclusive Z(→ee) boson plus jets production in pp collisions at s√ = 1.96 TeV, based on 1.7 fb-1 of data collected by the CDF experiment. Inclusive jet measurements are performed as function of pTjet and jet multiplicity for jets in the region of pTjet > 30 GeV/c and |yjet | < 2.1. Results are compared to NLO pQCD predictions and are found to be in good agreement.

Inclusive Search for Squark and Gluino Production at CDF
We present preliminary results on the search for squark and gluino production in proton-antiproton collisions at s = 1.96 TeV using 1.1 fb −1 of CDF Run II data. Events with multiple jets of hadrons and large missing transverse energy in the final state are studied within mSUGRA framework and assuming R-parity conservation. No excess with respect to Standard Model predictions is observed. In a mSUGRA scenario with A 0 = 0 , μ 0 and tan β = 5 , we exclude masses up to about 380 GeV / c 2 at 95% C.L. in the region where gluino and squark masses are similar.

The ALICE Silicon Drift Detector system
The project of the two Silicon Drift Detector (SDD) layers of the ALICE Inner Tracking System is reviewed, with details on the barrel construction and on the front-end electronics. The results on the SDD spatial resolution are reported as obtained in the 2000 beam test from a whole drift region of the detector.

Next-to-eikonal corrections in the CGC: gluon production and spin asymmetries in pA collisions
A bstractWe present a new method to systematically include corrections to the eikonal approximation in the background field formalism. Specifically, we calculate the subleading, power-suppressed corrections due to the finite width of the target or the finite energy of the projectile. Such power-suppressed corrections involve Wilson lines decorated by gradients of the background field — thus related to the density - of the target. The method is of generic applicability. As a first example, we study single inclusive gluon production in pA collisions, and various related spin asymmetries, beyond the eikonal accuracy.

Coherence effects between the initial and final state radiation in a dense QCD medium
Abstract In these proceedings contribution we review our recent results of medium modifications to the coherence pattern between the initial and final state radiation. We study single gluon production off a highly energetic parton that undergoes a hard scattering and subsequently crosses a dense QCD medium of finite size. Multiple scatterings lead to a partial suppression of the interferences between different emitters that opens the phase space for large angle emissions. We briefly discuss the generalization of this setup to describe gluon production in the case of pA collisions by including finite length and energy corrections. The configuration studied here may have phenomenological consequences in high-energy nuclear collisions.

The front-end system of the silicon drift detectors of ALICE
The ALICE experiment at CERN will have an inner tracker made of six barrels of semiconductor detectors. The two intermediate layers of the system will employ Silicon Drift Detectors (SDD) technology. The front-end electronics of the SDDs, which required the development of two full-custom integrated circuits, is reviewed in this paper. The design of the front-end hybrid is discussed and results obtained with full-size prototypes are presented.

A very forward luminosity monitor for the ALEPH detector at LEP
Abstract The design of a very small angle luminosity monitor for the ALEPH detector at LEP is described. The detector consists of four calorimeter modules made of alternating layers of tungsten and scintillators plus one layer of silicon strips for shower localization. Tests of the performance of the calorimeter and initial results obtained in LEP are also described.
