 2020-01-2314:22 [PUBDB-2020-00521] Preprint/Report et al The transverse momentum spectrum of low mass Drell-Yan production at next-to-leading order in the parton branching method [DESY 20-006; arXiv:2001.06488] The transverse momentum spectrum of low mass Drell-Yan (DY) production at low center-of-mass energies $\sqrt{s}$ is calculated by applying transverse momentum dependent (TMD) parton distributions obtained from the Parton Branching (PB) evolution method, combined with the next-to-leading-order (NLO) calculation of the hard process in the MCatNLO method. We compare our predictions with experimental measurements at low DY mass, and find very good agreement.

The search is based on events recorded in s=13  TeV proton-proton collisions with the CMS detector at the LHC, collected in 2016, and corresponding to an integrated luminosity of 35.9  fb-1.

The damage for a given dose is larger for lower dose rate exposures.

The results are based on a sample of proton–proton collisions at a center-of-mass energy of $13\,\text {Te}\text {V}$, collected by the CMS experiment at the LHC in 2016–2018 and corresponding to an integrated luminosity of 137$\,\text {fb}^{-1}$.

All searches make use of proton-proton collision data at $\sqrt{s}=$ 13 TeV, which were recorded with the CMS detector at the LHC in 2016, and correspond to an integrated luminosity of 35.9 fb$^{-1}$.

A prioritized, compact set of benchmark models is proposed, accompanied by studies of the parameter space of these models and a repository of generator implementations.
