If the Higgs mass is around 115 GeV, how many inverse femtobarns at 7 TeV are needed to find the Higgs?
Vanadium 50 said:As for what's delivered, the best week has the LHC averaging 20 pb-1/day now. Assume it runs twice this well for 18 more months and you get 11 fb-1. So it doesn't really matter if we are talking 17, 30 or 50.
petergreat said:According to the LHC website, on 1 May the luminosity was increased to 8.4e32 /cm^2/s, which corresponds to roughly 70/pb per day.

I stand by my original statement: 20/fb.I've found such a graph on Tommaso Dorigo's blog:... On the graph, 5/fb at 7 TeV gives a 2.7 sigma significance for a 115 GeV Higgs.
An inverse femtobarn (fb^-1) is a unit of measurement used in particle physics to represent the amount of data collected from particle collisions. It is equivalent to approximately 10^15 collisions.
The more inverse femtobarns collected, the higher the chances of detecting rare processes such as the production of the Higgs boson. This is because the Higgs boson is a very rare particle and requires a large amount of data to be observed.
7 TeV (teraelectronvolts) refers to the center-of-mass energy of the Large Hadron Collider (LHC), which is a particle accelerator used to collide protons at high energies. This energy level was used during the first run of the LHC from 2009-2013.
A total of 5 inverse femtobarns of data were collected at 7 TeV during the first run of the LHC. This data was used to confirm the existence of the Higgs boson in 2012.
The Higgs boson is a very rare and elusive particle, and requires a large amount of data to be observed. The more data collected, the higher the chances of detecting the Higgs boson and understanding its properties. Additionally, a larger dataset allows for more precise measurements and can potentially reveal other new particles or phenomena.
