[Hotlist] [DELPHI event] [Particle Physics] [Useful?] [Fun?] [Organisations] [People] [Mirrors] [Background] [Multimedia]
This is a picture from the DELPHI event display. It shows a representation of the detector and the results of an electron-positron collision at 161 GeV - sufficient energy to create a W+ and W-. Each W decays into a quark and antiquark each of which produces a jet of particles. The four jets are seen by the detector, shown in red, green, blue, and black.
LEP first achieved 161 GeV beams on the
morning of 9th July 1996 (I was there!).
DELPHI was lucky enough to be the first of the four the LEP experiments to
see such an event, making this the first-ever W+W- pair
produced in the uniquely clean conditions of
an e+e- collider.
Of course luck comes to those prepared, and it was no doubt due to the
excellent state of
the DELPHI
Slow Controls (OK, the
whole online system)
that we detected the event and identified it so quickly.
OK, that's the interesting stuff out of the way. Now on to some...

Please don't be offended if you aren't here. It's either because I don't know about your web page, or because it is already referenced from The OUSFG e-mail list.
OK, so my infobahn-cred has just gone down the toilet. Sigh...
