A novel sequence for reversible second-order nonlinear optical (NLO) molecular switching with protonation/deprotonation has been achieved and tuned as well. The NLO switching with first hyperpolarizabilities (beta(0)) as low as 14 x 10(-30) esu (Off-phase) and as large as 1189 x 10(-30) esu (On-phase) have been computed by using density functional theory (DFT). Remarkably large differences betw...
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...
Spin-dependent parton distributions in the polarized virtual photon are investigated in QCD up to the next-to-leading order (NLO). In the case Λ ≪ P 2 ≪ Q, where −Q (−P ) is the mass squared of the probe (target) photon, parton distributions can be predicted completely up to the NLO, but they are factorization-scheme-dependent. Parton distributions are analyzed in four different factorization s...
Abstract Recently, the ATLAS data of isolated three-photon production showed that next-to-leading order (NLO) collinear factorization is not enough to describe experimental data. Therefore, one needs calculate cross section beyond NLO, and as later, these can be well described by NNLO calculation within framework. However, it shown $$k_t$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML...
We report a next-to-leading order (NLO) calculation of the production of gaugino-like charginos (χ̃) and neutralinos (χ̃0) in association with gluinos (g̃) at hadron colliders, including the strong corrections from colored particles and sparticles. We provide predictions of inclusive cross sections at the Fermilab Tevatron and CERN LHC. The NLO contributions increase the sizes of the cross section...
Achieving the highest precision for theoretical predictions at the LHC requires the calculation of hard-scattering cross sections that include perturbative QCD corrections up to (N)NNLO and electroweak (EW) corrections up to NLO. Parton distribution functions (PDFs) need to be provided with matching accuracy, which in the case of QED effects involves introducing the photon parton distribution o...
