We present a strategy for the systematic extraction of a vast amount of detailed information on polarized parton densities and fragmentation functions from semi-inclusive deep inelastic scattering l +N → l + h+X, in both LO and NLO QCD. A method is suggested for estimating the errors involved in the much simpler, and therefore much more attractive, LO analysis. The approach is based upon a nove...

We present a determination of the parton distribution functions of the proton in which NLO and NNLO fixed-order calculations are supplemented by NLLx small-x resummation. Deep inelastic structure functions are computed consistently at NLO+NLLx or NNLO+NLLx, while for hadronic processes small-x resummation is included only in the PDF evolution, with kinematic cuts introduced to ensure the fitted...

OBJECTIVE The purpose of this study was to assess the ability of label-free multimodal nonlinear optical (NLO) microscopy to characterize, and thus enable quantitative in situ analyses of, different atherosclerotic lesion types, according to the original scheme suggested by the AHA Committee. METHODS AND RESULTS Iliac arteries were taken from 24 male Ossabaw pigs divided into lean control and...

Results are presented from an ongoing analysis of direct photon production with the STAR experiment at RHIC. The direct photon measurement in d+Au collisions and the π 0 spectrum in p+p collisions are found to be in agreement with NLO pQCD calculations.

An organic nonlinear optical single crystal of L-tartaric acid-nicotinamide (LTN) has been grown by slow evaporation of the saturated solution at constant temperature of 45 C. The grown crystal is subjected to single crystal X-ray diffraction analysis to identify the space group and unit cell parameters. The crystalline quality of LTN has been investigated by high-resolution X-ray diffractometr...

Following our ab initio nonlinear optical (NLO) materials design guidelines, in this Letter, we discovered a novel type of structure to realize potential deep-ultraviolet (DUV) NLO performance the classical beryllium borate system. By densely stacking NLO-active layered frameworks, key scheme for structural evolution from (Be2BO3F2) layers KBe2BO3F2 (KBBF) (Be2BO5H3) berborite is illustrated. B...

Measurements of the inclusive jet cross section and the dijet angular distribution using data from the Tevatron are presented. Comparisons to NLO QCD show good agreement below 250 GeV, but CDF data show an excess at higher ET ; qualitative agreement is seen between the CDF and DØ cross sections. Analysis of the dijet angular distributions exclude quark compositeness below 2.1 TeV.

Polarized parton distribution functions are determined by using world data from the longitudinally polarized deep inelastic scattering experiments. A new parametrization of the parton distribution functions is adopted by taking into account the positivity and the counting rule. From the fit to the asymmetry data A1, the polarized distribution functions of u and d valence quarks, sea quarks, and...
