Fiducial Drell-Yan production at the LHC improved by transverse-momentum resummation at N$^4$LL+N$^3$LO | | Tobias Neumann

14 Jul 2022 | | Abstract: | Drell-Yan production is one of the precision cornerstones of the LHC, serving
as calibration for measurements such as the $W$-boson mass. Its extreme
precision at the level of 1% challenges theory predictions at the highest
level. We present the first independent calculation of Drell-Yan production at
order $alpha_s^3$ in transverse-momentum ($q_T$) resummation improved
perturbation theory. Our calculation reaches the state-of-the-art through
inclusion of the recently published four loop rapidity anomalous dimension and
three loop massive axial-vector contributions. We compare to the most recent
data from CMS with fiducial and differential cross-section predictions and find
excellent agreement at the percent level. Our resummed calculation including
the matching to $Z$+jet production at NNLO is publicly available in the
upcoming CuTe-MCFM 10.3 release and allows for theory-data comparison at an
unprecedented level. | | Source: | arXiv, 2207.07056 | | Services: | Forum | Review | PDF | Favorites | |
