Taking a closer look at LHC
In addition to the Higgs Boson, dozens of new hadrons have been discovered with collision data at the LHC during Run 1 and Run 2. Most of them have been found in the LHCb experiment.
The table below shows the discoveries announced from April 2012 to July 2022, and is taken from the Patrick Koppenburg-Website
