A simple energy loss model and its applications for silicon detectors

The energy loss of charged particles in silicon can be approximated by a simple analytical model. With help of measured charge deposits in individual channels of hit clusters their position and energy can be estimated. Deposits below threshold and saturated values are treated properly, resulting in a wider dynamic range. The proposed method gives improvements on both hit position and energy residuals. The model is successfully applied to track differential energy loss estimation and to detector gain calibration tasks.

Optimized differential energy loss estimation for tracker detectors

The estimation of differential energy loss for charged particles in tracker detectors is studied. The robust truncated mean method can be generalized to the linear combination of the energy deposit measurements. The optimized weights in case of arithmetic and geometric means are obtained using a detailed simulation. The results show better particle separation power for both semiconductor and gaseous detectors.

Improved primary vertex finding for collider detectors

Primary vertex finding for collider experiments is studied. The efficiency and precision of finding interaction vertices can be improved by advanced clustering and classification methods, such as agglomerative clustering with fast pairwise nearest neighbor search, followed by Gaussian mixture model or k-means clustering.

New method of particle identification with tracker detectors

Tracker detectors can be used to identify charged particles based on their global chi value obtained during track fitting with the Kalman filter. This approach builds upon the knowledge of detector material and local position resolution, using the known physics of multiple scattering and energy loss. The proposed method is independent of the traditional way of identification using deposited energy. The performance for present LHC experiments is demonstrated.

Soft physics capabilities of CMS in p-p and Pb-Pb

The CMS experiment will provide good quality measurements of yields and spectra of identified charged and neutral particles, both in p-p and heavy-ion collisions, thus contributing to the study of soft hadronic physics at the LHC energies.

Low pT Hadronic Physics with CMS

The pixel detector of CMS can be used to reconstruct very low pT charged particles down to about 0.1 GeV/c. This can be achieved with high efficiency, good resolution and a negligible fake rate for elementary collisions. In the case of central PbPb collisions the fake rate can be kept low for pT > 0.4 GeV/c. In addition, the detector can be employed for identification of neutral hadrons (V0s) and converted photons.

Centrality control of hadron-nucleus interactions by detection of slow nucleons

Slow nucleons emitted during a hadron-nucleus interaction can give information on the centrality, impact parameter of the collision. The aim of this note is to provide the reader with the important characteristics of the slow nucleons, focusing on their spectra, correlations. This study tries to build on evidences, hence more weight is put on experimental results than on models.

Recent NA49 results on Pb+Pb collisions at CERN SPS

In the spirit of establishing a fair reference for nucleus-nucleus collisions, results on stopping and baryon transfer, correlations of the p+p interaction and their consequences are shown. In the discussion of new results from nucleus-nucleus collisions the emphasis is on strange meson and baryon production at different energies - for the first time at 40 GeV A - with the study of light nuclei.
