Summary
Magnetic moments of baryon have played a vital role in understanding the internal structure of baryons. However, measurements have been restricted to light and strange baryons only. Heavy baryons have been studied in the last 10 years and precision spectroscopy has been allowed to determine the mass of all charmed baryons and excited states. Also lifetimes of all charmed baryons have by now been determined with small uncertainties showing harmed baryons to be the shortest living weakly decaying states with their lifetimes in the order of a few hundred femtoseconds.
Magnetic moments of baryons are typically measured by their spin rotation in magnetic fields. For short living particles high effective magnetic fields can be produced by channeling of particles through bent crystal planes, causing spin rotation. This principle has been shown at an experiment in the 1990’s at FNAL. However, the field scales with Lorentz Gamma and thus requires very high energy particles. High energies are in addition needed to provide large Lorentz boosts allowing the particle to traverse crystals of suitable length. Such energies can only be obtained using TeV beams, obtainable from an extracted LHC beam. Provided that transverse particle polarization as observed for hyperons at large transverse momenta can also be assumed for charmed baryons, spin procession could be observed using two body decays of charmed baryons offering sufficient analyzing power.
