The H1 and ZEUS combined data set on Neutral Current (NC) and Charged Current (CC) ep and ep inclusive cross sections is used as the input for next-to-leading order (NLO) and next-to-next-to-leading order (NNLO) QCD parton density function (PDF) fits resulting in a new preliminary PDF set called HERAPDF2.0 (prel.). The analysis yields small experimental uncertainties and includes estimates for ...

The nonlinear optical (NLO) properties of induced transmission filters (ITFs) based on Ag are experimentally determined using white light continuum pump-probe measurements. The experimental results are supported using simulations based on the matrix transfer method. The magnitude of the NLO response is shown to be 30 times that of an isolated Ag film of comparable thickness. The impacts of desi...

From the chemical bond viewpoint, the second order nonlinear optical (NLO) responses of some typical borate crystals with various crystal structures have been quantitatively studied. The correlations between structural characteristics and second order NLO properties of selected borate crystals are discussed. Calculations show that the isolated BO3 infrastructure is advantageous for borate cryst...

Abstract. Fragmentation functions are determined for pions, kaons, and nucleons by a global analysis of charged-hadron production data in electron-positron annihilation. The optimum functions are obtained in both leading order (LO) and next-to-leading order (NLO) of αs. It is important that uncertainties of the fragmentation functions are estimated in this work by the Hessian method. We found t...

We compute the next-to-leading order perturbative QCD corrections to the correlators of nucleon interpolating currents in relativistic nuclear matter. The main new result is the calculation of the O(αs) perturbative corrections to the coefficient functions of the vector quark condensate in matter. This condensate appears in matter due to the violation of Lorentz invariance. The NLO perturbative...

R = FL/2xF1, in longitudinally polarized DIS off various different targets (p, n, d) have become available in the past two years: E142, E143, and SMC have presented their final data sets [ 1], and new results from HERMES, E154, and E155 have been reported recently [ 2]. Since none of these measurements were included in our original NLO QCD analysis [ 3], it seems to be appropriate to reanalyse ...

p-Nitroaniline presents the typical motif of a second-order nonlinear optically (NLO) active molecule. However, because of its crystallization in an antiparallel and hence centrosymmetric structure, the NLO activity is lost. In this contribution, the p-nitroaniline motif was built successfully into the MIL-53 metal-organic framework. More precisely, MIL-53 was synthesized with 2-amino-5-nitrote...

We review the methods developed for combining the parton shower approximation to QCD with fixed-order perturbation theory, in such a way as to achieve next-toleading-order (NLO) accuracy for inclusive observables. This has made it possible to generate fully-simulated hadronic final states with the precision and stability of NLO calculations. We explain the underlying theory of the existing meth...

With the rapid developments of the all-solid-state deep-ultraviolet (deep-UV) lasers, the good nonlinear optical (NLO) crystal applied in this spectral region is currently lacking. Here, we design two novel NLO carbonates KBeCO3F and RbAlCO3F2 from the first-principles theory implemented in the molecular engineering expert system especially for NLO crystals. Both structurally stable crystals po...
