---+!! %MAKETEXT{"Welcome to the [_1] web" args="%WEB%"}% %TOC% ---++ 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 Λ<sub>b</sub> → Λ μ<sup>+</sup> μ<sup>-</sup> analysis. * *Cristina Lazerroni:* Working on the rare decay K → piμ<sup>+</sup>μ<sup>-</sup> analysis. Also leads the UK effort on the NA62 experiment. * *Simone Bifani*: Research Fellow in Particle Physics. Currently working on [[https://twiki.cern.ch/twiki/bin/view/LHCbPhysics/Bd2KstarMuMuAndOtherEWPenguins][electroweak penguin decays]]<span style="background-color: transparent"> </span><span style="background-color: transparent">and [[https://twiki.cern.ch/twiki/bin/viewauth/LHCbPhysics/ElectroweakPhysics][electroweak physics studies]].</span> * *Sasha Mazurov:* Most recent analysis of [[https://inspirehep.net/record/1315113/][Χ<sub>b</sub>(3P), Χ<sub>b1,2</sub>(1P)]], now [[https://github.com/LHCbDev/lhcbpr-api][developing]] the new performance and regression testing framework LHCbPR for simulation and more general use. * *Tonino Sergi:* working on K → piμ<sup>+</sup>μ<sup>-</sup> 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. * *Phil Ilten*: working on Dark Photon searches, HLT trigger and Pythia simulations for LHCb. * *Jimmy !McCarthy:* graduated !PhD student ( [[http://etheses.bham.ac.uk/6247/][thesis]]). Carried out the search for Λb → Λ η(') decays, [[http://dx.doi.org/10.1007/JHEP09(2015)006][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, Λ<sub>b</sub> → pKμ<sup>+</sup>μ<sup>-</sup> , and EM benchmarking tests Geant4 * *Luca Pescatore:* graduated !PhD student. Currently finalising R<sub>K*</sub> analysis, previously on rare decay Λ<sub>b</sub> → Λμ<sup>+</sup>μ<sup>-</sup> from Run I data, including branching fraction and angular analysis ( [[http://dx.doi.org/10.1007/JHEP06(2015)115][JHEP 1506 (2015) 115]], set up hadronic and material benchmarking tests for Geant4. * *Nathanael Farley:* <span style="background-color: transparent"> 4th year !</span><span style="background-color: transparent">PhD</span><span style="background-color: transparent"> student.

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 [[General.DaVinci][DaVinci]] to fill an nTuple from Data or Monte Carlo. * Using [[ROOT][ROOT]] to analyse the nTuple. * Using the [[General.TMVA][TMVA]] tool to refine your selection. * Using [[RooFit][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][Gauss]] and Boole to perform simulations. * Using [[Panoramix][Panoramix]] to visualize the detector. * Writing XML for the detector [[Descriptions][Descriptions]] * Making a new release of [[Geant4][Geant4]] for LHCb. <a target="_blank" href="http://www.ep.ph.bham.ac.uk/twiki/bin/view/LHCb/LHCbSimulationValidation" title="Validation Studies">Validation Studies</a> ---++ Useful Links * [[http://www.lepp.cornell.edu/~pt267/files/notes/FlavorNotes.pdf%u200E][Just a Taste - Lectures on Flavor Physics]], Yuval Grossman (latex notes by Flip Tanedo), Cornell. * [[http://arxiv.org/pdf/1006.3534v1][related notes from 2009 summer schools]] * [[http://indico.cern.ch/conferenceDisplay.py?confId=225363][Course on Physics at the LHC]], LIP Portugal, 2013 (emphasis on GPDs rather than CMS, but useful nontheless)
