WG1/6: Joint session (WG1/6: Structure Functions and Parton Densities + Future Experiment)
- Robert Samuel Thorne (University College London (UK))
The HERAPDF2.0 parton densities represent the current state of the art in determining the longitudinal structure of the proton using data from Deep Inelastic Scattering (DIS) experiments alone. Their precision is at the few percent level at intermediate Bjorken-x, but deteriorates fast for x-->1 and also below x~10^-3. The high x region in particular can also be constrained using LHC data,...
This work presents the next-to-leading order calculation of the heavy
quark production contributions to the structure functions F4 and F5
within the ACOT formalism in deep inelastic scattering. These struc
ture functions have been largely overlooked in the past, mainly due to
the experimental challenges associated with their measurement. How
ever, forthcoming experimental advancements,...
Recent studies suggest that global fits of Parton Distribution Functions (PDFs) might inadvertently 'fit away' signs of new physics in the high-energy tails of the distributions measured at the high luminosity programme of the LHC (HL-LHC). This could lead to spurious effects that might conceal key BSM signatures and hinder the success of indirect searches for new physics. In this talk, we...
We explore the potential for extracting the longitudinal proton structure function FL(x, Q2) at the future Electron-Ion Collider (EIC) through a Rosenbluth separation method. The impacts of differing assumptions on systematic uncertainties and beam energy scenarios are investigated. With a sufficiently large number of centre of mass energy configurations, the EIC will measure FL with an...
Motivated by the ion-collision program at the Large Hadron Collider, plans for its high-luminosity upgrade, and on-going discussions for multi-TeV future hadron colliders, we systematically investigate hard-scattering, Standard Model processes in many-TeV ion-ion collisions. We focus on the symmetric beam configurations for Pb-208, Xe-131, C-12, and the proton (for reference), catalog total...
