Seminar: Strange and fragile - Creation of fragile antimatter at the LHC

• Benjamin Doenigus (Institut für Kernphysik Goethe-Universität Frankfurt)

The high collision energies reached at the Large Hadron Collider (LHC) at CERN lead to significant production rates of fragile objects, i.e. objects whose binding energies are small compared to the average kinetic energy of the particles produced in the system. Such objects are, for instance, light (anti-)nuclei and (anti-)hypernuclei. The most extreme example here is the hypertriton, a bound state of a proton, a neutron and a $\Lambda$ hyperon, where the separation energy of the $\Lambda$ is only around 130 keV. Such states, from anti-deuteron up to anti-alpha nuclei, are nevertheless created and observed in the hot + rough environment of proton-proton and heavy-ion collisions at the LHC. The reached temperatures are higher than 156 MeV, corresponding to 1.8 x 10$^{12}$ K. Selected highlights of measurements of these fragile objects will be presented.
