F.S., explaining how the typical nucleus of analysis group in HEP works.
Want to boil water in less than a trillionth of a second?
Now you can, if you are at the Hamburg Center for Free-Electron Laser Science and can find someone to build your theoretical concept.
Still, heating water 600 degrees Celsius in just half a picosecond seems like a fun application. If it ever does get built, it will be the fastest water-heating method on earth.
In 1989 the CDF experiment was sitting on its first precious bounty of proton-antiproton collisions, delivered by the Tevatron collider at the unprecedented energy of 1.8 TeV. One of the first measurements that was produced was the measurement of the mass of the Z boson, which was at the time known with scarce precision by the analysis of a handful of candidates produced by the CERN SppS collider, at a third of the Tevatron energy.
It could be in a billion years, it could start tomorrow, but physicists have long predicted that the universe may one day collapse, and that everything in it will be compressed to a small hard ball.
Like a lot of things, it just takes a little mathematics to conclude that the risk of a collapse is even greater than previously thought.
No, this is not an article about top models. Rather, the subject of discussion are models that predict the existence of heavy partners of the top quark.
"During the years 1962 to 1964 a debate developed about whether the Goldstone theorem could be evaded. Anderson pointed out that in a superconductor the Goldstone mode becomes a massive plasmon mode due to its electromagnetic interaction, and that this mode is just the longitudinal partner of transversely polarized electromagnetic modes, which also are massive (the Meissner effect!). Ths was the first description of what has become known as the Higgs mechanism.
Inspired by my friend Peter Woit's openness in discussing his work in progress
(a thick textbook on the foundations of quantum mechanics), I feel compelled to come out here about my own project.
I'm speaking of bare particles. "Heroes" is maybe too pathetic, but blocks or "bricks" would be OK since everything is made of them despite their
being non-observable. Why are they non-observable? Because they are
non-interacting particles or particles "before interaction". Inaccessible, for short.
Just a quick link to allow you to browse a very nice set of pictures taken at CERN by Andri Pol. The subjects are physicists in their daily activities - brainstorming at the blackboard, cycling around the lab, bitching about the mess in the common coffee room, or working at various pieces of hardware:
