Linking chromospheric activity and magnetic field properties for late-type dwarf stars / BCool Collaboration
Spectropolarimetric data allow for simultaneous monitoring of stellar chromospheric $\log{R^{\prime}_{\rm{HK}}}$ activity and the surface-averaged longitudinal magnetic field, $B_l$, giving the opportunity to probe the relationship between large-scale stellar magnetic fields and chromospheric manifestations of magnetism. [...]

Measurement of antiproton production from antihyperon decays in $pHe$ collisions at $\sqrt{s_{NN}}=110$ GeV / Collaboration, Lhcb
The interpretation of cosmic antiproton flux measurements from space-borne experiments is currently limited by the knowledge of the antiproton production cross-section in collisions between primary cosmic rays and the interstellar medium. [...]
