Dijet measurements provide an excellent tool not only to probe high transverse-momentum parton interactions to study QCD but also to look for signs of new phenomena beyond the Standard Model.
Read article 'ALICE tracks charm energy loss in the QGP'
The first direct observation of the suppression of charmed mesons at high transverse-momentum in head-on nucleus–nucleus collisions indicates that charm quarks suffer a strong loss of energy in hot...
