Quantum Dynamics of Rotational Transitions in CN (X2Σ+) by H+ Collisions
Frontiers in Chemistry, 2021 Collisional cross-sections of inelastic rotational excitations of CN in its ground electronic state (X2Σ+) by H+ scattering are studied by the exact quantum mechanical close-coupling (CC) method at very low collision energies (0–600 cm−1) relevant to ...

Total Photonic and Hadronic Cross-sections [PDF]
, 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.

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 ...

N3LO+N3LL QCD improved Higgs pair cross sections
Journal of High Energy Physics, 2023 We report a new calculation of the soft-gluon threshold resummation for the Higgs boson pair production in the dominant production mode — gluon-gluon fusion — up to the next-to-next-to-next-to-leading logarithmic (N3LL) accuracy.

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.

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 ...
