title: PACIAE 2.1: An updated issue of the parton and hadron cascade model PACIAE 2.0

description: Abstract We have updated the parton and hadron cascade model PACIAE 2.0 (cf. Ben-Hao Sa, Dai-Mei Zhou, Yu-Liang Yan, Xiao-Mei Li, Sheng-Qin Feng, Bao-Guo Dong, Xu Cai, Comput. Phys. Comm. 183 (2012) 333.) to the new issue of PACIAE 2.1. The PACIAE model is based on PYTHIA. In the PYTHIA model, once the hadron transverse momentum p T is randomly sampled in the string fragmentation, the p x and p y components are originally put on the circle with radius p T randomly. Now it is put on the circumference o... Title of program: PACIAE version 2.1 Catalogue Id: AEKI_v2_0 Nature of problem PACIAE is based on PYTHIA. In the PYTHIA model, once the generated particle/parton transverse momentum (p T ) is randomly sampled, the p x and p y components are randomly placed on the circle with radius of p T . This strongly cancels the final state transverse momentum asymmetry developed from the initial spatial asymmetry.

In certain cases a mixture of two multipolarities may occur in a single transition. The amount of mixing, i.e. the mixing ratio, is determined by the structure of the nuclear levels involved.

We have used a published model, extended to include long-ranged Coulomb interactions, to study defects in iron.

description: Abstract Susyno is a Mathematica package dedicated to the computation of the 2-loop renormalisation group equations of a supersymmetric model based on any gauge group (the only exception being multiple U(1) groups) and for any field content. Title of program: Susyno Catalogue Id: AEMX_v1_0 Nature of problem Calculating the renormalisation group equations of a supersymmetric model involves using long and complicated general formulae [1, 2]. In addition, to apply them it is necessary to know the Lagrangian in its full form.

title: Bremsstrahlung cross section for a point, spinless target

The cross section, which includes recoil of the target particle, is valid at relativistic energies and wide angles. Title of program: BREMPNT Catalogue Id: ABRV_v1_0 Nature of problem The differential cross section for bremsstrahlung was originally calculated by Bethe and Heitler.

In addition, as discussed by Maximon, de Miniac and Aniel, the direct use of the Bethe-Heitler cross- section is complicated by a sharp structure which can lead to the loss of 10 or more ...
