The Diphoton $q_T$ spectrum at N$^3$LL$^\prime$+NNLO

Neumann, Tobias

Understand

We present a $q_T$-resummed calculation of diphoton production at order N$^3$LL$^\prime$+NNLO.

To reach the primed level of accuracy we have implemented the recently published three-loop $\mathcal{O}(\alpha_s^3)$ virtual corrections in the $q\bar{q}$ channel and the three-loop transverse momentum dependent beam functions and combined them with the existing infrastructure of CuTe-MCFM, a code performing resummation at order N$^3$LL.
While the primed predictions are parametrically not more accurate, one typically observes from lower orders and other processes that they are the dominant effect of the next order.
We include in both the $q\bar{q}$ and loop-induced $gg$ channel the hard contributions consistently together at order $\alpha_s^3$ and find that the resummed $q\bar{q}$ channel without matching stabilizes indeed.
