Abstract
Inclusive jet cross section measurements from the ATLAS, CDF, CMS, D0, H1, STAR, and ZEUS experiments are explored for determinations of the strong coupling constant alpha _{text {s}} (M_{text {Z}}). Various jet cross section data sets are reviewed, their consistency is examined, and the benefit of their simultaneous inclusion in the alpha _{text {s}} (M_{text {Z}}) determination is demonstrated. Different methods for the statistical analysis of these data are compared and one method is proposed for a coherent treatment of all data sets. While the presented studies are based on next-to-leading order in perturbative quantum chromodynamics (pQCD), they lay the groundwork for determinations of alpha _{text {s}} (M_{text {Z}}) at next-to-next-to-leading order.
Highlights
The strong coupling constant, αs, is one of the least precisely known fundamental parameters in the Standard Model of particle physics
While the presented studies are based on next-to-leading order in perturbative quantum chromodynamics, they lay the groundwork for determinations of αs(MZ) at next-to-next-to-leading order
Inclusive jet cross section data from different experiments at various particle colliders with jet transverse momenta ranging from 7 GeV up to 2 TeV are explored for determinations of αs(MZ) using next-to-leading order predictions
Summary
The strong coupling constant, αs, is one of the least precisely known fundamental parameters in the Standard Model of particle physics. A determination of αs at NNLO from jet measurements in hadron-hadron collisions is still not readily achievable, because the new NNLO pQCD calculations are computationally very demanding and cannot yet be repeated quickly for different parton distribution functions (PDFs) or values of αs(MZ). In preparation of such a determination, it is desirable to study a simultaneous analysis of data sets from different processes and experiments.
