Twist-3 fragmentation effects for ALT in light hadron production from proton–proton collisions

Twist-3 fragmentation effects for ALT in light hadron production from proton–proton collisions

We compute the contribution from the twist-3 fragmentation function for light hadron production in collisions between transversely and longitudinally polarized protons, i.e., p↑p→→hX, which can cause a double-spin asymmetry (DSA) ALT. This is a naïve T-even twist-3 observable that we analyze in coll...
