They are obtained as a function of the total fractional energy and invariant mass for any di-hadron combination in the same hemisphere as defined by the thrust event-shape variable and its axis. Since same-hemisphere dihadrons can be assumed to originate predominantly from the same initial parton, di-hadron fragmentation functions are probed. These di-hadron fragmentation functions are needed as an unpolarized baseline in order to quantitatively understand related spin-dependent measurements in other processes and to apply them to the extraction of quark transversity distribution functions in the nucleon. The di-hadron cross sections are obtained from a 655 fb?1 data sample collected at or near the ??4S? resonance with the Belle detector at the KEKB asymmetric-energy e?e? collider. ? 2017 American Physical Society.[SDGs]SDG7journal article10.1103/PhysRevD.96.0320052-s2.0-85049865379
