Single Inclusive Hadron Production in DIS at Small $x$: Next to Leading Order Corrections

A new subtraction scheme at NLO exploiting the privilege of kT-factorization

“…This factorization becomes phenomenologically relevant for scattering events in which the final-state products are boosted towards one initial-state direction, implying that one of the collinear momentum fractions was much smaller than the other. It has already been applied at NLO precision for selected processes [18][19][20][21][22][23][24]. The matrix elements with space-like initial-state partons cannot be obtained from a trivial kinematic continuation of completely on-shell matrix elements, and need to be defined properly.…”

Diffractive single and di-hadron production at NLO in a saturation framework

“…In this work, we investigate the diffractive single and di-hadron production at small-𝑥 through the Balitsky's shockwave formalism [1] at the next-to-leading order (NLO). This new class of processes are golden channels to investigate gluon tomography in the nucleon and nuclei [2][3][4] and widen the list of processes useful for testing saturation at the NLO [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22].…”
