Symbol b.

A unit of area. A barn is 10−28 m2 (100 fm2), about the cross-sectional area of a uranium nucleus.

A barn expresses the cross section of any scattering process, which relates to the probability of interaction between small particles.

Sample size at CERN is often expressed in femtobarns and luminosity is expressed in inverse femtobarns.

Round brackets

Round brackets (also called parentheses) are mainly used to separate off information that isn’t essential to the meaning of the rest of the sentence. If you removed the bracketed material the sentence would still make perfectly good sense. For example: 

Mount Everest (8848 metres) is the highest mountain in the world.

grammar, punctuation

Brout-Englert-Higgs mechanism
