On 13^th of Sep­tem­ber, the LHCb exper­i­ment at CERN pre­sented a mea­sure­ment of the masses of two par­tic­u­lar par­ti­cles with a pre­ci­sion that is unprece­dented at a col­lider like the LHC. Until then, pre­cise stud­ies of these “char­mo­nium” par­ti­cles were only pos­si­ble with purpose-​built exper­i­ments and seemed impos­si­ble to be achieved at a hadron col­lider.
