Earlier today, at the 128th LHCC Open session meeting, both ATLAS and CMS experiments demonstrated for the first time candidate events whose signatures are compatible with the decay of a pair of top quarks in the nuclear environment of proton-Lead (pPb) collisions at a center-of-mass energy of 8.16 TeV. Currently, and while steadily moving to the last beam dumps for 2016 (Monday 5th), LHC runs with beam reversal mode at the same center-of-mass energy, where the directions of p and Pb bunches are reversed since not all LHC experiments are symmetric.
