Scattering Cross Sections and Lorentz Violation [PDF]

open access: yes, 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

Neutrino cross sections and nuclear structure [PDF]

open access: yes, 2008
The effects of the theoretical uncertainties in the description of neutrino-nucleus cross sections for supernova neutrino energies are investigated.Comment: Contribution to NOW 2008, Conca Specchiulla (Otranto, Italy), September 6-13 ...

Higgs cross sections: a brief overview

open access: yesEPJ 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 ...

The systematics of neutron reaction cross sections [PDF]

open access: yesEPJ 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.

Total Photonic and Hadronic Cross-sections [PDF]

open access: yes, 2001
We discuss total cross-sections within the context of the QCD calculable mini-jet model, highlighting its successes and failures. In particular we show its description of $\gamma \gamma \to hadrons$ and compare it with OPAL and L3 data.

Capture cross sections from (p,d) reactions

open access: yesEPJ 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 ...

Neutrino absortion cross sections in supernova environment [PDF]

open access: yes, 2001
We study charged-current neutrino cross sections on neutronrich nuclei in the mass $A\sim60$ region. Special attention is paid to environmental effects, i.e. finite temperature and density, on the cross sections.

Notes on entanglement wedge cross sections

open access: yesJournal of High Energy Physics, 2019
We consider the holographic candidate for the entanglement of purification E P , given by the minimal cross sectional area of an entanglement wedge E W .

Dimensional schemes for cross sections at NNLO

open access: yesEuropean 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 ...
