  We calculate the next to leading order corrections to dihadron production in
Deep Inelastic Scattering (DIS) at small x using the Color Glass Condensate
formalism for the case when the virtual photon is transverse polarized. Similar
to the case of longitudinal photon exchange all UV and soft singularities
cancel while the collinear divergences are absorbed into quark and
antiquarkhadron fragmentation functions. Rapidity divergences lead to JIMWLK
evolution of dipoles and quadrupoles which describe multiple-scatterings of the
quark antiquark dipole on the target proton/ nucleus and contain all the QCD
dynamics of the target leading to a finite final result for the dihadron
production cross section.
