Precision test of the muon-Higgs coupling at a high-energy muon collider
Jürgen Reuter, Tao Han, Wolfgang Kilian +4
We explore the sensitivity of directly testing the muon-Higgs coupling at a high-energy muon collider. This is strongly motivated if there exists new physics that is not aligned wi…
The persistent nonperturbative charm enigma
Marco Guzzi, T. J. Hobbs, Keping Xie +3
The question of the existence and possible magnitude of nonperturbative (often called "intrinsic") charm in the proton has long confounded attempts to cleanly isolate such a contri…
Report of the Topical Group on Physics Beyond the Standard Model at Energy Frontier for Snowmass 2021
Tulika Bose, Antonio Boveia, Caterina Doglioni +318
This is the Snowmass2021 Energy Frontier (EF) Beyond the Standard Model (BSM) report. It combines the EF topical group reports of EF08 (Model-specific explorations), EF09 (More gen…
Heavy Neutral Leptons at the Electron-Ion Collider
Brian Batell, Tathagata Ghosh, Tao Han +1
The future Electron-Ion Collider (EIC) at Brookhaven National Laboratory, along with its primary capacity to elucidate the nuclear structure, will offer new opportunities to probe…
Heavy-flavor impact on CTEQ-TEA global QCD analyses
Marco Guzzi, Alim Ablat, Sayipjamal Dulat +5
We discuss heavy-flavor production at hadron colliders in recent global QCD analyses to determine parton distribution functions (PDFs) in the proton. We discuss heavy-flavor treatm…
Precision QCD, Hadronic Structure & Forward QCD, Heavy Ions: Report of Energy Frontier Topical Groups 5, 6, 7 submitted to Snowmass 2021
M. Begel, S. Hoeche, M. Schmitt +47
This report was prepared on behalf of three Energy Frontier Topical Groups of the Snowmass 2021 Community Planning Exercise. It summarizes the status and implications of studies of…
Report of the Topical Group on Top quark physics and heavy flavor production for Snowmass 2021
Reinhard Schwienhorst, Doreen Wackeroth, Kaustubh Agashe +68
This report summarizes the work of the Energy Frontier Topical Group on EW Physics: Heavy flavor and top quark physics (EF03) of the 2021 Community Summer Study (Snowmass). It aims…
Report of the Topical Group on Electroweak Precision Physics and Constraining New Physics for Snowmass 2021
Alberto Belloni, Ayres Freitas, Junping Tian +65
The precise measurement of physics observables and the test of their consistency within the standard model (SM) are an invaluable approach, complemented by direct searches for new…
Understanding PDF uncertainty on the boson mass measurements in CT18 global analysis
Jun Gao, DianYu Liu, Keping Xie
We study the dependence of the transverse mass distribution of the charged lepton and the missing energies on the parton distributions (PDFs) adapted to the boson mass measurem…
Parton distributions need representative sampling
Aurore Courtoy, Joey Huston, Pavel Nadolsky +3
In global QCD fits of parton distribution functions (PDFs), a large part of the estimated uncertainty on the PDFs originates from the choices of parametric functional forms and fit…
The PDF4LHC21 combination of global PDF fits for the LHC Run III
Richard D. Ball, Jon Butterworth, Amanda M. Cooper-Sarkar +19
A precise knowledge of the quark and gluon structure of the proton, encoded by the parton distribution functions (PDFs), is of paramount importance for the interpretation of high-e…
Electroweak fragmentation at high energies: A Snowmass White Paper
Tao Han, Yang Ma, Keping Xie
In particle collisions at energies higher than the mass scale involved, the collinear splitting becomes the dominant phenomena. Suitable descriptions of the physics in this regime…

High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large number of particles along the beam collision axis, outside of the acceptance of existing L…
Snowmass 2021 whitepaper: Proton structure at the precision frontier
S. Amoroso, A. Apyan, N. Armesto +54
An overwhelming number of theoretical predictions for hadron colliders require parton distribution functions (PDFs), which are an important ingredient of theory infrastructure for…
The strong coupling constant: State of the art and the decade ahead
D. d'Enterria, S. Kluth, G. Zanderighi +55
Theoretical predictions for particle production cross sections and decays at colliders rely heavily on perturbative Quantum Chromodynamics (QCD) calculations, expressed as an expan…
