Abstract
In this talk I report recent results on heavy flavor physics from ATLAS and CMS. It includes two topics: spectroscopy of open or hidden beauty hadrons and studies of rare B decays of the type b → sμ+μ−. The former one is aimed to collect new information on the properties of beauty hadrons which helps to gain better understanding of QCD. And the latter one provides a good opportunity of searching for New Physics, the effects beyond the Standard Model. The discussed results were obtained with the Run 1 data or Run 2 data .
Highlights
The ATLAS [1] and CMS [2] experiments at LHC are designed mainly for high-pt physics
In the Standard Model (SM) these decays proceed through suppressed penguin or box diagrams
The measurements of flavor changing neutral current (FCNC) decays are sensitive to the phenomena beyond the SM
Summary
The ATLAS [1] and CMS [2] experiments at LHC are designed mainly for high-pt physics (studies of the Higgs boson, precision measurements of the Standard Model processes and parameters and numerous searches for New Physics including Dark Matter particles and SUSY particles). Both experiments are contributing intensively in heavy flavor physics. The redundant muon system with large rapidity coverage provides high-purity muon-ID with standalone δpt/pt = 10% This is a very efficient hardware Level 1 trigger and highly flexible High Level Trigger with paths dedicated to b-hadron specific decays with muons in the final state. It is good pt resolution in tracker with high efficiency (> 99% in CMS) and good secondary vertex reconstruction with the impact parameter resolution down to ≈ 15 μm
