Following Sanchez’s approach we investigate the effect of scalar mass in the absorption and emission problems of 4d Schwarzschild black hole. The absorption cross sections for arbitrary angular momentum of the scalar field are computed numerically in the full range of energy by making use of the analytic near-horizon and asymptotic solutions and their analytic continuations. The scalar mass mak...

This report describes the conversion of an existing large-cross-sectionalarea tunnel into a shock tube and the evaluation of the capabilities of this facility for blast loading and response studies of full-scale and large-scale structural elements. Also included are the results from a preliminary test series of full-scale wall panels conducted as part of the evaluation program and the design of...

The differential cross-section for pair production of top quarks with high transverse momentum is measured in 20.3 fb−1 of proton-proton collisions at a center-of-mass energy of 8 TeV. The measurement is performed for tt events in the leptonþ jets channel. The cross-section is reported as a function of the hadronically decaying top quark transverse momentum for values above 300 GeV. The hadroni...

For regularized hard potentials cross sections, the solution of the spatially homogeneous Boltzmann equation without angular cutoff lies in Schwartz’s space S(RN ). The proof is presented in full detail for the two-dimensional case, and for a moderate singularity of the cross section. Then we present those parts of the proof for the general case, where the dimension, or the strength of the sing...
