QCDMoriond Discussion

Thursday March 22, 2207

• The aim of this meeting is to prepare future Moriond.

• In 1966, when I started the first Rencontres de Moriond, the main objectives of the meeting are :

•Promote exchanges and collaboration between experimentalists and theorists

•Promote young physicists in giving them a priority for giving a talk.

Every year, in each Moriond session, we have a discussion meeting in order to find out if we still

fulfill the "founding" objectives

As many « institutions », Moriond is getting older every year (42nd Moriond this year : since 1966), we may become a club of "senior physicists".

It is why your PARTICIPATION and your HELP is much needed to maintain Moriond in the right

track.

and Bolek Pietrzyk, some numbers and graphs

QCD 2007

Experimentalists vs Theorist :• We try in Moriond to have a ratio of 60% of

experimentalists and 40% of theorists.

• This year : 85 experimentalists : 66%; 43 theorists : 33%, not too far of our wishes
