Dear all,

At 11am I'll give a short 'lecture' on decaytreefitter over Vidyo. It is for UK PhD students, but I guess everybody is welcome. You can find details below.

Cheers. Wouter

Dear all,

We are pleased to announce that there will be an LHCb-UK student meeting next Tuesday (April 9th), featuring a presentation by Wouter Hulsbergen discussing the DecayTreeFitter tool and its use in LHCb. This is a tool which is being used by an increasing number of analyses, so please come along to find out how it works and how it could be applied to your own analysis!

Ahead of the meeting, Wouter asked us to circulate a couple of links that give some background information on DecayTreeFitter:

1) The original paper outlining the method http://arxiv.org/abs/physics/0503191

2) Some lectures from Wouter on tracking http://www.nikhef.nl/~wouterh/topicallectures/ (especially Parts 1 & 6)

The meeting will start at 10am UK time (11am CERN time). The Indico page can be found here:

https://indico.cern.ch/conferenceDisplay.py?confId=245278

There is a Vidyo booking attached to the meeting, the details are:

Name of the room: LHCb_UK_Student_Meeting Extension: 9235227 PIN: 2924

For those at CERN, the meeting will be in the usual room, 32/S-C22. Coffee and pastries will be provided.

We hope to see many of you there!

Best Regards,

Laurence, Steve, Thomas and Sam
