Electroweak couplings of the Higgs boson at a multi-TeV muon collider
/ Han, Tao (Pittsburgh U.) ; Liu, Da (UC, Davis, QMAP) ; Low, Ian (Northwestern U. ; Argonne) ; Wang, Xing (UC, San Diego)
We estimate the expected precision at a multi-TeV muon collider for measuring the Higgs boson couplings with electroweak gauge bosons, $HVV$ and $HHVV\ (V=W^\pm,Z)$, as well as the trilinear Higgs self-coupling $HHH$. At very high energies both single and double Higgs productions rely on the vector-boson fusion (VBF) topology. [...]

WIMPs at High Energy Muon Colliders
/ Han, Tao (Pittsburgh U.) ; Liu, Zhen (Maryland U.) ; Wang, Lian-Tao (Chicago U., EFI ; Chicago U., KICP) ; Wang, Xing (UC, San Diego)
The Weakly Interacting Massive Particle (WIMP) paradigm is one of the most compelling scenarios for particle dark matter (DM). We show in this paper that a high energy muon collider can make decisive statements about the WIMP DM, and this should serve as one of its main physics driver cases. [...]

High energy leptonic collisions and electroweak parton distribution functions
/ Han, Tao (Pittsburgh U.) ; Ma, Yang (Pittsburgh U.) ; Xie, Keping (Pittsburgh U.)
In high-energy leptonic collisions well above the electroweak scale, the collinear splitting mechanism of the electroweak gauge bosons becomes the dominant phenomena via the initial state radiation and the final state showering. We point out that at future high-energy lepton colliders, such as a multi-TeV muon collider, the electroweak parton distribution functions (EW PDFs) should be adopted as the proper description for partonic collisions of the initial states. [...]

Quark and gluon contents of a lepton at high energies
/ Han, Tao (Pittsburgh U.) ; Ma, Yang (Pittsburgh U.) ; Xie, Keping (Pittsburgh U.)
In high-energy leptonic collisions, such as at a multi-TeV muon collider, the collinear splittings of the electroweak (EW) gauge bosons and leptons are the dominant phenomena, and the scattering processes should thus be formulated in terms of the EW parton distribution functions (EW PDFs). We complete this formalism in the Standard Model to include the QCD sector and evaluate the quark and gluon PDFs inside a lepton at the double-log accuracy. [...]

Towards a Muon Collider

A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions at high luminosity and 10 TeV centre of mass energy are being investigated by the recently-formed International Muon Collider Collaboration. [...]

Report of the Topical Group on Electroweak Precision Physics and Constraining New Physics for Snowmass 2021
/ Belloni, Alberto (Maryland U.) ; Freitas, Ayres (Pittsburgh U.) ; Tian, Junping (Tokyo U., ICEPP) ; Alcaraz Maestre, Juan (Madrid, CIEMAT) ; Apyan, Aram (Brandeis U.) ; Azartash-Namin, Bianca (Oklahoma U.) ; Azzurri, Paolo (INFN, Pisa) ; Banerjee, Swagato (Louisville U.) ; Beyer, Jakob (DESY) ; Bhattacharya, Saptaparna (Northwestern U.) et al.
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 particles, to determine the existence of physics beyond the standard model (BSM). [...]
