This contribution is devoted to the description and discussion of those frameworks which lead to correlations among partons in the initial stage that, if not washed out by strong final state interactions and hadronisation – that we will assume in the following, may lead to azimuthal asymmetries...
A comprehensive numerical model of a continuous PVD process has to deal with various phenomena that complicate numerical simulations, such as evaporation at the melt surface, the rapid increase in the Mach number of the vapor flow ranging from incompressible to compressiblesupersonic flow, the high ...
We compare our predictions with several single-, double-differential and total cross sections from six distinct measurements published by the H1 or ZEUS collaboration. A quantitative comparison of NLO and NNLO predictions with the data is presented. We further study the scale dependence of the NNLO...
a collection of Chinese mythology, there is a description about Yinglong: Yinglong is a creature living in the heaven, and it helps the Yellow Emperor to kill Chiyou and Kuafu. In the tribe war, the Yellow Emperor defeats the Yan Emperor. Later, Chiyou declares a war to revenge for the ...

Despite a notable progress in theoretical description of heavy quarkonia production done over past few decades, the quarkonia production mechanism, as well as their propagation and dissociation in a hot medium, is considered to be an important probe for the medium created in heavy-ion collisions ...
The production of charmed mesons containing the light quarks u,d and s is found to be compatible with a description in which the hard scattering is followed by a factorisable and universal hadronisation process. This is a preview of subscription content, log in via an institution to check ...
A detailed description of the H1 detector can be found elsewhere [7–10]. The coordinate system of H1 is defined such that the positive z axis is in the direction of the proton beam (forward direction) and the nominal interaction point is located at z=0. The polar angle θ is then def...
In the regions where the perturbative calculations are expected to work well, the CS results are almost one order of magnitude smaller than the HERA data. The NRQCD results obtained by using the three sets of the LDMEs have their own advantages in the description of the data in specific ...
description is provided by the\({\mathcal{O}}(\alpha_{{\text{s}}}^3)\)calculation. Too few events are predicted at the lowest x∼10-4, especially for topologies with two forward jets. This hints to large contributions at low x from initial state radiation of gluons close to the ...
