“…Figure 4 illustrates the eect of adding G 21 and C 2 to the LL plus NLL prediction of the 2{ jet rate. The above results are consistent with another recent calculation [18], however, the errors given there are rather large and the possible eect of non-logarithmic contribution was neglected.…”

We show that an Ansatz to resum all leading and next{to{leading logarithms in the theoretical prediction for the 2{jet rate in e + e hadrons, where jets are dened with the k t {algorithm, is consistent with a full O( submitted to Phys.Lett.B

“…The GMVFNS was recently implemented for direct [23] and single-resolved [24] collisions as well as for ep collisions with quasireal photons [25]. In the case of !…”
We study the photoproduction of a D meson in association with a hadron jet at next-to-leading order in the parton model of QCD with nonperturbative fragmentation functions extracted from LEP1 data of e e ÿ annihilation. The transverse-momentum and rapidity distributions recently measured at DESY HERA in various kinematic ranges nicely agree with our theoretical predictions. This provides a useful test of the universality and the scaling violations of the fragmentation functions predicted by the factorization theorem. These comparisons also illustrate the significance of the charm component in the resolved photon. This is elaborated by investigating the cross section distributions in x obs and cos .
“…Since the inception of the chemical studies of the constituents of the Viburnums, the presence of a glycosidal substance has been either hinted or reported (5)(6)(7)(8)(9). In 1942, Evans, Harne and Krantz (3) described the isolation of a glycosidal principle in crystalline form from an authentic sample of Viburnum prunifolium, which produced the characteristic relaxation of uterine strips.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
