 The pixel detector based tracklet reconstruction algorithm in ALICE / Elia, D ; Grosse-Oetringhaus, J.F ; Nicassio, M ; Virgili, T This note describes a method to reconstruct signals in the two silicon pixel detector layers compatible with tracks coming from the main interaction vertex, namely tracklets. The basic algorithm strategy and its performance are illustrated.. ARDA-Note-2009-005; ALICE-INT-2009-021.- Geneva : CERN, 2009 Fulltext: PDF;

 Measurement of pseudorapidity density of charged particles in proton-proton collisions with the ALICE Pixel detector / Elia, D ; Ghidini, B ; Nicassio, M This note describes a procedure for measuring the pseudorapidity density distribution of charged particles, based on the tracklets reconstructed with the silicon pixel layers. Results on proton-proton Monte Carlo samples are presented.. ARDA-Note-2009-004; ALICE-INT-2009-029.- Geneva : CERN, 2009 Fulltext: PDF;

 Vertex reconstruction for proton-proton collisions in ALICE / Bruna, E (Yale U.) ; Dainese, A (INFN, Padua) ; Masera, M (INFN, Turin ; Turin U.) ; Prino, F (INFN, Turin ; Turin U.) Reconstructing the interaction vertex is a challenging task in the low multiplicity environment of pp collisions at the LHC. The two innermost layers of the Inner Tracking System (ITS), made of pixels, allow to obtain a first estimate of the vertex position, which can be provided also in a quasi-online mode, since only the local reconstruction is used.

 Alignment of the ALICE Inner Tracking System with cosmic-ray tracks / Bombonati, C et al The ALICE Inner Tracking System (ITS) consists of six cylindrical layers of silicon detectors with three different technologies; in the outward direction: two pixel, two drift and two strip layers. The number of parameters to be determined in the spatial alignment of the 2198 sensor modules of the ITS is about 13,000.
