CMS is a general purpose experiment, designed to study the physics of pp collisions at 14
TeV at the Large Hadron Collider (LHC). It currently involves more than 2000 physicists from …

Although the Standard Model (SM) of particle physics has so far been tested to exquisite
precision, it is considered to be an effective theory up to some scale Λ≈ TeV. The prime …

Good geometrical alignment is essential to fully benefit from the excellent intrinsic resolution
of the CMS silicon tracker. Since the tracker consists of about 20000 independent silicon …

This paper provides a review of the main algorithms for inclusive b-tagging based on track
impact parameters. The performance of these algorithms is investigated for jets in different Pt …

The positions of the silicon modules of the CMS tracker will be known to O (100 μm) from
survey measurements, mounting precision and the hardware alignment system. However, in …

This note describes a study of the potential of the CMS experiment to discover Z'gauge
bosons in the Z'--> mu+ mu-decay channel. Unbinned maximum likelihood fits to mu+ mu …

Software alignment is quite important for a tracking detector to reach its ultimate position
accuracy and momentum resolution. We developed a new alignment algorithm for the BESIII …

The Alignment of the CMS tracker will require to determine about 10^ 5 alignment
parameters. The Millepede program, a linear least-squares algorithm, is a promising …

Abstract The Large Hadron Collider (LHC) will dominate the high energy physics program in
the coming decade. The discovery of the standard model Higgs boson and the discovery of …

The impact of misalignment on the performance of the CMS silicon tracking devices Pixel
and silicon Strip tracker is studied. Misalignment scenarios are used which are expected to …
