Models for total, elastic and diffractive cross sections

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
The LHC has brought much new information on total, elastic and diffractive cross sections, which is not always in agreement with extrapolations from lower energies. The default framework in the Pythia event generator is one case in point. In this article

ON THE IMPORTANCE OF SECOND-ORDER RESPONSE SENSITIVITIES TO NUCLEAR DATA IN REACTOR PHYSICS UNCERTAINTY ANALYSIS [PDF]

open access: yesEPJ Web of Conferences, 2021
This invited keynote presentation compares the relative importance of 1st-order versus 2nd-order sensitivities of the leakage response of an OECD/NEA benchmark (polyethylene-reflected plutonium sphere) to the nuclear data characterizing this benchmark ...

The reaction rate of radiative n8Li capture in the range from 0.01 to 10 T9

open access: yesFrontiers in Astronomy and Space Sciences, 2023
Within the modified potential cluster model (MPCM) with forbidden states, the total cross sections are calculated for capture in the ground and first excited states of the 9Li nucleus in the n8Li channel in the energy range from 10−5 eV to 5 MeV based on

Comments on high-energy total cross sections in QCD

open access: yesPhysics Letters B, 2015
We discuss how hadronic total cross sections at high energy depend on the details of QCD, namely on the number of colours Nc and the quark masses.

Total and Differential Cross Sections for Higgs and Top-Quark Production

open access: yesUniverse, 2018
I present theoretical calculations for Higgs-boson and top-quark production, including high-order soft-gluon corrections. I discuss charged-Higgs production in association with a top quark or a W boson, as well as single-top and top-antitop production ...

Total hadronic cross sections at high energies in holographic QCD

open access: yesPhysics Letters B, 2019
We present our analysis on high energy hadron–hadron scattering in the framework of the holographic QCD. Combining the Brower–Polchinski–Strassler–Tan Pomeron exchange kernel and gravitational form factors of the involved hadrons which are obtained by ...
