Improving the parameterization of silicon vertex detector resolution distributions for the tagging of bottom and charm-flavored hadron decays for the Collider Detector at Fermilab experiment
This project was concerned with parameterizing the silicon vertex detector (SVX) resolution distributions, especially those of the r-φ plane, so that bottom quark jets (b jets) could be tagged more efficiently with a "jet probability" algorithm. Fits of the sum of four zero-mean Gaussians were produced on cuts of the data that incorporated the number of SVX shared hits (0, 1, 2, >=3), the numbe...
متن کاملThe Belle Silicon Vertex Detector
The silicon vertex detector of the Belle experiment has been built to provide the vertex information of B meson decays at the KEKB accelerator. It consists of three cylindrical layers of double sided, double metal silicon sensors read out by VA1 chips. The analog signals are transmitted to a system of fast analog-to-digital converters and are reduced on a system based on Motorola Digital Signal...
متن کاملThe H1 silicon vertex detector
The design, construction and performance of the H1 silicon vertex detector is described. It consists of two cylindrical layers of double sided, double metal silicon sensors read out by a custom designed analog pipeline chip. The analog signals are transmitted by optical fibers to a custom designed ADC board and are reduced on PowerPC processors. Details of the design and construction are given ...
متن کاملDetermination of the Jet Energy Scale at the Collider Detector at Fermilab
A precise determination of the energy scale of jets at the Collider Detector at Fermilab at the Tevatron pp̄ collider is described. Jets are used in many analyses to estimate the energies of partons resulting from the underlying physics process. Several correction factors are developed to estimate the original parton energy from the observed jet energy in the calorimeter. The jet energy response...
متن کاملSVX’, the new CDF silicon vertex detector
The Collider Detector at Fermilab (CDF) radiation hardened silicon vertex detector (SVX’) is described. The new detector has several improvements over its predecessor such as better signal to noise and higher efficiency. It is expected to have a radiation tolerance in excess of 1 Mrad. It has been taking data for several months and some preliminary results are shown.
