Atomic data for astrophysics. II. New analytic fits for photoionization cross sections of atoms and ions [PDF]
, 1996 We present a complete set of analytic fits to the nonrelativistic photoionization cross sections for the ground states of atoms and ions of elements from H through Si, and S, Ar, Ca, and Fe.

Cross Sections are History [PDF]
SSRN Electronic Journal, 2013 Although cross section relationships are often taken to indicate causation, and especially the important impact of economic growth on many social phenomena, they may, in fact, merely reflect historical experience, that is, similar leader-follower country patterns for variables that are causally unrelated.

The systematics of neutron reaction cross sections [PDF]
EPJ Web of Conferences, 2020 The parameterized theoretical formulae of excitation functions for (n, 2n) and (n, γ) reactions have been established, and for (n,tot), (n,non), (n,3n), (n,p), (n,d), (n,t), (n,3 He) and (n,α) have been recommended.

Scattering Cross Sections and Lorentz Violation [PDF]
, 2002 To date, a significant effort has been made to adddress the Lorentz violating standard model in low-energy systems, but little is known about the ramifications for high-energy cross sections. In this talk, I discuss the modified Feynman rules that result

Dimensional schemes for cross sections at NNLO
European Physical Journal C: Particles and Fields, 2020 So far, the use of different variants of dimensional regularization has been investigated extensively for two-loop virtual corrections. We extend these studies to real corrections that are also required for a complete computation of physical cross ...

Higgs cross sections: a brief overview
EPJ Web of Conferences, 2012 I briefly review the status of theoretical predictions for the inclusive production of a Standard Model Higgs boson at hadron colliders. In particular, I focus on the main production channels: gluon-gluon fusion, vector boson fusion and associated ...

Capture cross sections from (p,d) reactions
EPJ Web of Conferences, 2017 Cross sections for compound-nuclear reactions involving unstable targets are important for many applications, but can often not be measured directly. Several indirect methods have been proposed to determine neutron capture cross sections for unstable ...
