We report the first double differential cross sections of two charged pionsand kaons ($e^+e^- \rightarrow hhX$) in electron-positron annihilation as afunction of the fractional energies of the two hadrons for any charge andhadron combination. The dependence of these di-hadron cross sections on thetopology (same, opposite-hemisphere or anywhere) is also studied with the helpof the event shape variable thrust and its axis. The ratios of these di-hadroncross sections for different charges and hadron combinations directly shedlight on the contributing fragmentation functions. For example, we find thatthe ratio of same-sign pion pairs over opposite-sign pion pairs drops towardhigher fractional energies where disfavored fragmentation is expected to besuppressed. These di-hadron results are obtained from a $655\,{\rm fb}^{-1}$data sample collected near the $\Upsilon(4S)$ resonance with the Belle detectorat the KEKB asymmetric-energy $e^+ e^-$ collider. Extending the previouslypublished single-pion and single-kaon cross sections, single-proton ($e^+e^-\rightarrow pX$) cross sections are extracted from a $159\,{\rm fb}^{-1}$ datasub-sample.

Inclusive cross sections for pairs of identified light charged hadrons and for single protons in $e^+e^-$ at $\sqrt{s}=$ 10.58 GeV
