Picric acid has a tendency to form stable picrate compounds with various organic molecules due to the presence of active electron cloud and ionic bonds (Yamaguchi et al., 1988). In the past two decades, organic nonlinear optical (NLO) picrate crystals have attracted the scientists and technologists due to their potential applications in the area of photonics including optical information proces...
We present NLO QCD results for Wbb̄ and Zbb̄ production at the Tevatron including full bottomquark mass effects. We study the impact of QCD corrections on both total cross-section and invariant mass distribution of the bottom-quark pair. Including NLO QCD corrections greatly reduces the dependence of the tree-level cross-section on the renormalization and factorization scales. We also compare our...
Combined multimodal nonlinear optical (NLO) microscopies were used to detect and quantify morphological changes associated with stroma and epithelial transformation in colon cancer. Our findings provide complementary information about tissue microstructure, displaying distinctive patterns between normal and malignant human colon. Additionally, we have demonstrated the usefulness of using fixed ...
An NLO photon parton parametrization is presented based on the existing F γ 2 measurements from e +e− data and the low-x proton structure function from ep interactions. Also included in the extraction of the NLO parton distribution functions are the dijets data coming from γp → j1+j2+X. The new parametrization is compared to other NLO parametrizations. TPJU – 2/2005 TAUP 2797-05 March 2005 e-ma...
Differential cross sections of charged particles in inelastic pp collisions as a function of pT have been measured at [Formula: see text] at the LHC. The pT spectra are compared to NLO-pQCD calculations. Though the differential cross section for an individual [Formula: see text] cannot be described by NLO-pQCD, the relative increase of cross section with [Formula: see text] is in agreement with...
This is the user’s manual of MC@NLO 3.4. This package is a practical implementation, based upon the HERWIG event generator, of the MC@NLO formalism, which allows one to incorporate NLO QCD matrix elements consistently into a parton shower framework. Processes available in this version include the hadroproduction of single vector and Higgs bosons, vector boson pairs, heavy quark pairs, single to...

Details of the calculation of the non-forward BFKL kernel at next-to-leading order (NLO) are offered. Specifically we show the calculation of the two-gluon production contribution. This contribution was the last missing part of the kernel. Together with the NLO gluon Regge trajectory, the NLO contribution of one-gluon production and the contribution of quark-antiquark production which were foun...
We report on the extraction of the higher twist contributions to F2 and R = σL/σT from global NLO and NNLO QCD fits to lepton nucleon scattering data over a wide range of Q 2. The NLO fits require both target mass and higher twist contributions at low Q 2. However, in the NNLO analysis, the data are described by the NNLO QCD predictions (with target mass corrections) without the need for any si...
