Energy-Aware Compression-Computation Co-Adaptation for Latency Minimization in Multi-User Semantic Communication
Loc X. Nguyen, Yumin Park, Avi Deb Raha +4
Deep joint source-channel coding-enabled (DeepJSCC) semantic communication (SemCom) has excelled at delivering high perceptual quality at low channel-bandwidth ratios, which positi…
Impact of Z-boson transverse-momentum resummation on PDF determination
Juan M. Cruz-Martinez, Emanuele R. Nocera, Luca Rottoli +1
We study the impact of small-transverse-momentum resummation for neutral-current Drell-Yan lepton-pair production on the determination of collinear parton distribution functions (P…
Higher-order effects in amplitude-assisted polarisation extraction with machine-learning techniques
Juan M. Cruz-Martinez, Jakob Linder, Mathieu Pellen +2
With increasing experimental precision, the prospect of extracting the polarisation of electroweak gauge bosons is becoming particularly attractive. To this end, regression and cla…
Hyperoptimisation algorithm for the next generation of PDF determinations: ensemble regression with an unbiased selection model
Juan M. Cruz-Martinez, Tommaso Giani, Tanjona R. Rabemananjara
We present a new automated procedure for selecting fitting methodologies in the determination of parton distribution functions (PDFs), based on a hyperoptimisation algorithm using…
Assessing the Impact of Fitting Methodology at aNLO with FPPDF: an Open Source Tool for Extracting Parton Distribution Functions in the Hessian Approach
J. M. Cruz-Martinez, T. Giani, L. A. Harland-Lang
We present a new public code, FPPDF, to perform global fits of parton distribution functions (PDFs). The fitting methodology follows that implemented by the MSHT collaboration, nam…
A Determination of at Accuracy from a Global PDF Analysis
The NNPDF Collaboration, Richard D. Ball, Andrea Barontini +6
We present a determination of the strong coupling from a global dataset including both fixed-target and collider data from deep-inelastic scattering and a variety of ha…
