    Description: Author(s): Song Mao, Li Gang, Zhou Ya-Jin, Guo Jian-You, and Ma Zheng-Wei We calculate the next-to-leading order (NLO) QCD corrections to J / ψ associated with W + b production from top quark decay. Our results show that the decay width for process t → J / ψ + W + + b + X at the leading order is significantly enhanced by the NLO QCD corrections. This process has the potential to be dete...

    Stable Solitons in Three Dimensional Free Space without the Ground State: Self-Trapped Bose-Einstein Condensates with Spin-Orbit Coupling (2015)

    Publication Date: 2015-12-18
    Description: Author(s): Yong-Chang Zhang, Zheng-Wei Zhou, Boris A. Malomed, and Han Pu By means of variational methods and systematic numerical analysis, we demonstrate the existence of metastable solitons in three dimensional (3D) free space, in the context of binary atomic condensates combining contact self-attraction and spin-orbit coupling, which can be engineered by available exp… [Phys.

    X-Ray Diffraction and Imaging Study of Imperfections of Crystallized Lysozyme with Coherent X-Rays (2003)

    Publication Date: 2019-07-18
    Description: Phase-sensitive x-ray diffraction imaging and high angular-resolution diffraction combined with phase contrast radiographic imaging are employed to characterize defects and perfection of a uniformly grown tetragonal lysozyme crystal in symmetric Laue case. The fill width at half-maximum (FWHM) of a 4 4 0 rocking curve measured from the original crystal is approximately 16.7 arcseconds, and defects, which include point defects, line defects, and microscopic domains, have been clearly observed in the diffraction images of the crystal. The observed line defects carry distinct dislocation features running approximately along the 〈110〉 growth front, and they have been found to originate mostly at a central growth area and occasionally at outer growth regions. Individual point defects trapped at a crystal nucleus are resolved in the images of high sensitivity to defects. Slow dehydration has led to the broadening of the 4 4 0 rocking curve by a factor of approximately 2.4. A significant change of the defect structure and configuration with drying has been revealed, which suggests the dehydration induced migration and evolution of dislocations and lattice rearrangements to reduce overall strain energy. The sufficient details of the observed defects shed light upon perfection, nucleation and growth, and properties of protein crystals.
