Abstract:
With Pb-Pb colisions in the high luminosity LHC.,exotic obiects are created containing, in addition to thetamiiar un, down and stranee auarks also one, two, and mavbe even three charm auarks. we wi brethdescribe the nature of these obiects and show that the production yields of these obiects are expected to bestrongly enhanced in nuclear collisions compared to measurements  in proton-proton colisions, we wil presennew technologies based on ultra-thin curved silicon wafers that have been  ceve oneo to cetect such ohiects andshow the results of measurements with the uperaded AlICE detector that demonstrate strong evidence for thepredicted enhancement,In the next decade, a newexnerimentAee3)amost excusiveyAaseo onsdetectors will be built. With this experiment the predicted multiple charm hierarchy will be inyestigated to shecight on the mechanism under ying the decontement of(charm) quarks.
