Description
In ultra-relativistic collisions at the Large Hadron Collider (LHC)
light (anti-)(hyper-)nuclei are produced with significant yields,
especially in collisions between lead nuclei. In addition, these
collisions give the possibility to search for light exotic bound
states of baryons. Light nuclei are identified using the excellent
particle identification capabilities of the Time Projection Chamber
(TPC) and the Time-Of-Flight (TOF) detector of the ALICE experiment.
Transverse-momentum spectra and production yields of light composite
objects such as (anti-)nuclei and the (anti-)(hyper)triton will be
presented. To understand their production mechanism the comparison of
the results obtained for the three collision systems, pp, p-Pb and
Pb-Pb and at different energies will be discussed. They are then
compared with predictions from thermal and coalescence models. In
addition, we will present results from searches for weakly-decaying
light exotic states, such as the Lambda-Lambda (H-dibaryon) and the
Lambda-neutron bound states.
