4.

The LHCb design allowed the study of collisions of particle beams with a gas injected inside the VELO volume, making it similar to a fixed-target experiment; this setup is usually referred to as "SMOG".

In 2015, analysis of the decay of bottom lambda baryons in the LHCb experiment revealed the apparent existence of pentaquarks, in what was described as an "accidental" discovery.

10.

In March 2021, LHCb announced that the anomaly in lepton universality crossed the "3 sigma" statistical significance threshold, which translates to a p-value of 0.
