Production of a Higgs boson accompanied by two jets via gluon fusion.

Real-emission corrections to gg-->H, which lead to H+2 jet events, are calculated at order alpha(4)(s). Contributions include top-quark triangles, boxes, and pentagon diagrams and are evaluated analytically for arbitrary top mass m(t). This new source of H+2 jet events is compared to the weak-boson fusion cross section for a range of Higgs boson masses. The heavy top-mass approximation appears to work well for intermediate Higgs-boson masses, provided that the transverse momenta of the final-state partons are smaller than the top-quark mass.

Confusion points and constant-luminance planes for trichromats, protanopes and deuteranopes.

The confusion points of dichromats are derived from the constant-luminance planes of trichromats, protanopes and deuteranopes experimentally defined by heterochromatic-flicker photometry: (1) the zero-luminance planes of the observers considered in this experiment intersect almost exactly in a line that crosses the plane of the chromaticity diagram in the tritanopic-confusion point and confirm that the short-wavelength sensitive cones can be considered to have no contribution to luminance; (2) protanopic- and deuteranopic-confusion points are taken as being defined by the intersection of the tangent line to the long-wavelength region of the spectrum locus and the zero-luminance plane for protanopes and deuteranopes, respectively.

Uniform-scale chromaticity diagram with angular coordinates in zero-curvature space.

Dichromats have angular color discrimination in the usual chromaticity diagrams. Normal trichromatic vision is obtained by combining tritanopic and deuteranopic vision. In this paper, a new pair of angular variables is introduced from which, by a suitable transformation, a uniform-scale chromaticity diagram in zero-curvature space is obtained.
