Explanation:

Fermilab, the American particle accelerator, has released first results from its “muon g-2” experiment.

• These results spotlight the anomalous behaviour of the elementary particle called the muon.
• The muon g-2 experiment measured the extent of the anomaly and the Fermilab announced recently that “g” deviated from the amount predicted by the Standard Model. 

Muons

• Muons are elementary subatomic particles similar to the electron but heavier than electron.
• They belong to lepton family and has two forms, the negatively charged muon and its positively charged antiparticle.
• A muon is relatively unstable, with a lifetime of only 2.2 microseconds before it decays by the weak force into an electron and two kinds of neutrinos.
• Muons are expected to have a value of 2 for its magnetic moment, labelled “g”.

Hence both statements are correct.
