Welcome to the LHCb web

Organisation

We joined the LHCb experiment early in 2011, after first data taking so our responsibilities are for core software and not experimental hardware. This section will keep track of who is working on what. Please feel free to edit your section if I have missed anything out.

  • Nigel Watson: Head of the LHCb group. Responsible for implementing new versions of Geant4 within the LHCb framework, and testing performance against previous versions. Working on the rare decay Λb → Λ μ+ μ- analysis.
  • Cristina Lazzeroni: Working on the rare decay K → piμ+μ- analysis. Also leads the UK effort on the NA62 experiment.
  • Simone Bifani: Research Fellow in Particle Physics. Currently working on electroweak penguin decays and electroweak physics studies.
  • Sasha Mazurov: Most recent analysis of Χb(3P), Χb1,2(1P), now developing the new performance and regression testing framework LHCbPR for simulation and more general use.
  • Tonino Sergi: working on K → piμ+μ- analysis, coordinating integration tests of elementary module for RICH upgrade, developing firmware for irradiation tests of FE board FPGA, carrying out PMT ageing tests, and responsible for RICH aspects of firmware on the TELL40 boards.
  • Mark Slater: Responsible for GRID operations and GANGA developement.
  • Dmitry Popov: Maintenance and development of the LHCbPR framework for LHCb software performance monitoring.
  • Phil Ilten: working on Dark Photon searches, HLT trigger and Pythia simulations for LHCb.
  • Jimmy McCarthy: graduated PhD student ( thesis). Carried out the search for Λb → Λ η(') decays, JHEP 1509 (2015) 006. Optimised the Geant4 generator cuts used by LHCb in order to improve the performance of Monte Carlo productions, responsible for the XML description of the beam pipe supports.
  • Pete Griffith: graduated PhD student. Finalising the analysis, Λb → pKμ+μ- , and EM benchmarking tests Geant4
  • Luca Pescatore: graduated PhD student. Currently finalising RK* analysis, previously on rare decay Λb → Λμ+μ- from Run I data, including branching fraction and angular analysis ( JHEP 1506 (2015) 115, set up hadronic and material benchmarking tests for Geant4.
  • Nathanael Farley: 4th year !PhD student. Working on the search for B+c → K*0(892) K+and PMT ageing tests for RICH, as well as contributing to the development of LHCbPR.
  • Tim Williams: 4th year student, working on search for Λb → pK; η(') decay, EM benchmarking for Geant4.
  • Georgios Chatzikonstantinidis: 3rd year student, working on Λb → Λμ+μ (run I and II) angular analysis with moments; previously at Nikhef, masters on study of CPT and Lorentz-invariance violation in B s mixing
  • Kristian Zarebski: 3rd year student, working on search for K → πμ+μ- and maintaining the Radiation Length and Hadronic Multiplicity & Cross Section Tests for Sim10 validation via LHCbPR.
  • Ryan Calladine: 2nd year student, working on RK* measurement in Run 2 and Muon Multiple Scattering benchmarking tests for Sim10
  • Jonathan Plews: 1st year student, working on Drell-Yan to cross sections.

Local Meetings

We currently have regular meetings every Wednesday, 09:00 in the West 229 meeting room

Working Locally

CernVM can be used to access the LHCb software locally. The advantage to working locally is that it is a lot quicker than trying to run emacs etc. over the network.

Physics Analysis

These pages are aimed at giving a brief introduction to the tools needed for a physics analysis. It is supposed to be guide only to jog your memory and give some example code. Please refer to the manuals and tutorials for a full description of how everything works.

  • Using DaVinci to fill an nTuple from Data or Monte Carlo.
  • Using ROOT? to analyse the nTuple.
  • Using the TMVA tool to refine your selection.
  • Using RooFit? to perform fits to Data.

Simulations

These pages are aimed at giving a brief introduction to the tools needed to run simulations for your technical work. It is supposed to be guide only to jog your memory and give some example code. Please refer to the manuals and tutorials for a full description of how everything works.

  • Using Gauss? and Boole to perform simulations.
  • Using Panoramix? to visualize the detector.
  • Writing XML for the detector Descriptions?
  • Making a new release of Geant4? for LHCb.
