when is the LHC find out if higgs boson excist?
hamster143 said:The most likely three-sigma discovery target, assuming it's there at all and assuming no further engineering delays, is (as far as I know) two to three years from the time the collider is launched at full luminosity.
blechman said:The top quark was "discovered" in the early 1990's, but the actual announcement of its discovery was not until 1995.
Vanadium 50 said:That's not my recollection - and I was there. (Along with 900 other people, of course)
Tevatron "Run I" began in 1992. The 1992-1993 run led to the 1994 CDF paper http://arxiv.org/PS_cache/hep-ex/pdf/9405/9405005v1.pdf" . CDF was in a difficult position - there were not enough top candidate events for a discovery, but there were too many for an improved limit compared to their last paper - which had only 20% of the data. Hence a paper that didn't really answer the question "do you see it or not"?
In 1995, midway through the second half of Run I (50 pb-1 for D0 and 67 pb-1 for CDF), both experiments wrote "Observation" papers.
the_house said:There's certainly the possibility of finding something else first, but I'm not sure what they could find that would make the Higgs search irrelevant.
The LHC has already confirmed the existence of the higgs boson in 2012. However, ongoing experiments and data analysis continue to provide more information about this elusive particle.
The LHC uses high-energy particle collisions to recreate the conditions present in the early universe. Scientists then observe the products of these collisions, such as photons and particles, to identify the presence of the higgs boson.
The higgs boson is crucial in explaining how particles acquire mass. Its discovery confirmed the validity of the Standard Model of particle physics, which is a fundamental framework for understanding the behavior of matter and energy.
Yes, the discovery of the higgs boson has opened up new avenues for research and has the potential to lead to breakthroughs in areas such as dark matter, quantum gravity, and the origin of the universe.
The higgs boson is a key piece in the puzzle of the universe's fundamental building blocks. Its existence helps us understand how particles acquire mass and provides evidence for the theories that explain the origin and evolution of the universe.
