Feasibility of Beauty Baryon Polarization Measurement in Λ J/ψ decay channel by ATLAS-LHC
نویسندگان
چکیده
The possibility of beauty baryon polarization measurement by cascade decay angular distribution analysis in the channel Λ J/ψ → pπ−l+l− is demonstrated. The error analysis shows that in the proposed LHC experiment ATLAS at the luminosity 104pb−1 the polarization can be measured with the statistical precision better than δ = 0.010 for Λb and δ = 0.17 for Ξ 0 b .

Lambda-b Polarization in the LHC-ATLAS Experiment
Described here is the study of lambda-b polarization in the LHC-ATLAS experiment I have done with Prof. Homer Neal this summer. Our work has three main focuses, including predicting lambda polarization from quark-quark scattering models applied to p-p elastic collisions, modeling lambda polarization saturation, and simulating lambda-b events and polarization measurements in ATLAS using the λ0J/...
متن کاملCharm and Bottom Production Measurements at the LHC
Early data of the ATLAS and CMS experiments at the LHC will allow us to measure the cross sections for beauty and heavy quarkonia production in pp collisions at a center-of-mass energy of 14 TeV to a reasonable precision. Different experimental approaches employing single or di-muon triggered events and b-tagging methods are discussed. The potential for extracting the polarization of vector sta...

We discuss the feasibility of the observation of the signal from B c mesons in the ATLAS experiment of the LHC collider at a luminosity of ≈ 10 33 cm −2 s −1. In particular we address the decay mode B c →J/ψπ followed by the leptonic decay J/ψ→µ + µ − , which should permit an accurate measurement of the B c mass. We performed a Monte Carlo study of the signal and background concluding that a pr...

In particular, we address the decay mode B c →J/ψπ followed by the leptonic decay J/ψ→µ + µ − , which should permit an accurate measurement of the B c mass.

متن کاملMeasuring Supersymmetric Particle Masses at the LHC in Scenarios with Baryon–Number R-Parity Violating Couplings
The measurement of sparticle masses in the Minimal Supersymmetric Standard Model at the LHC is analysed, in the scenario where the lightest neutralino, the χ̃1, decays into three quarks. Such decays, occurring through the baryon-number violating coupling λ ijk, pose a severe challenge to the capability of the LHC detectors since the final state has no missing energy signature and a high jet mult...
