Report No.: DESY-24-035; arXiv:2403.10109

Abstract: The H1 Collaboration reports the first measurement of the 1-jettinessevent shape observable \tb in neutral-current deep-inelasticelectron-proton scattering (DIS). The observable \tb is equivalent to a thrust observable defined in the Breit frame.The data sample was collected at the HERA $ep$ collider in the years 2003--2007 with center-of-mass energy of $\sqrt{s}=319$ GeV, corresponding to an integrated luminosity of $351.1$ pb$^{-1}$. Triple differential cross sections are provided as a function of $\tau_1^b$, event virtuality $Q^2$, and inelasticity $y$, in the kinematic region $Q^2>150$ GeV$^2$.Single differential cross section are provided as a function of $\tau_1^b$ in a limited kinematic range.Double differential cross sections are measured, in contrast, integrated over $\tau_1^b$ and represent the inclusive neutral-current DIS cross section measured as a function of $Q^2$ and $y$.The data are compared to a variety of predictions and includeclassical and modern Monte Carlo event generators, predictions in fixed-orderperturbative QCD where calculations up to $\mathcal{O}(\alpha_s^3)$ areavailable for $\tau_1^b$ or inclusive DIS, and resummed predictions atnext-to-leading logarithmic accuracy matched to fixed orderpredictions at $\mathcal{O}(\alpha_s^2)$.These comparisons reveal sensitivity of the 1-jettiness observable to QCD partonshower and resummation effects, as well as themodeling of hadronization and fragmentation.Within their range of validity, the fixed-order predictions provide a good description of the data.Monte Carlo event generators are predictive over the full measured rangeand hence their underlying models and parameters can be constrained by comparing to the presented data.
