Measurements of hadron production at CMS

Intial State Radiation and Inclusive Hadron Production Measurements at Babar

The status of analysis of processes with hard photon emitted from the initial state (ISR) at BABAR is presented. We tag events by the presence of a hard photon in the detector, then reconstruct μμ and several exckusive hadronic final states. The invariant mass of the final state determines an effective collision center of mass energy at which these measurements can be compared with results from...

CMS Central Hadron Calorimeter

We present a description of the CMS central hadron calorimeter. We describe the production of the 1996 CMS hadron testbeam module. We show the results of the quality control tests of the testbeam module. We present some results of the 1995 CMS hadron testbeam. The design of the CMS detector starts with the 4 T solenoidal magnet of length 13 m and inner diameter 5.9 m. The magnet determines many...

Study of the Wz Production at Cms

The study of multiple gauge boson production at the TeV scale constitutes a unique opportunity to test the Standard Model (SM) of electroweak interactions at the highest possible energies. The production of WZ events via s-channel allows to probe triple gauge-boson couplings in modelindependent manner at the energies never attained before and improve our understanding of the gauge theory. Any d...

Measurements of B hadron lifetimes at CDF

Using data samples in excess of 1 fb collected by the CDF II detector we present several world’s best measurements of B hadron lifetimes. They include Bs meson lifetime in a flavor-specific decay mode, combining fully and partially reconstructed hadronic decays, B c meson lifetimes in semileptonic B + c → J/ψl X, l = μ, e decays and Λb baryon lifetime in Λ+c π − fully-reconstructed decays. In a...
