New measurements of the Collins asymmetries were performed by BABAR exploiting inclusive e+e− → h1h2 X annihilations (with h1,2 = π and/or K) mainly at the energy of the ϒ(4S), which corresponds to a squared transferred momentum Q2 ~ 110 GeV2c4. For the first time asymmetries following strange quarks fragmentation could be derived as a function of the fractional energy carried out by inclusively emitted hadron pairs.
