Adagio for Thermal Relics
Hooman Davoudiasl, Matthew Sullivan
A larger Planck scale during an early epoch leads to a smaller Hubble rate, which is the measure for efficiency of primordial processes. The resulting slower cosmic tempo can accom…
Report of the Topical Group on Higgs Physics for Snowmass 2021: The Case for Precision Higgs Physics
Sally Dawson, Patrick Meade, Isobel Ojalvo +78
A future Higgs Factory will provide improved precision on measurements of Higgs couplings beyond those obtained by the LHC, and will enable a broad range of investigations across t…
Role of dimension-eight operators in an EFT for the 2HDM
Sally Dawson, Duarte Fontes, Samuel Homiller +1
The Standard Model effective field theory (SMEFT) is the tool of choice for studying deviations of Higgs couplings from the Standard Model predictions. The SMEFT is an expansion in…
Future Circular Lepton Collider FCC-ee: Overview and Status
I. Agapov, M. Benedikt, A. Blondel +21
The worldwide High Energy Physics community widely agrees that the next collider should be a Higgs factory. Acknowledging this priority, in 2021 CERN has launched the international…
Complex Scalar Singlet Model Benchmarks for Snowmass
Shekhar Adhikari, Samuel D. Lane, Ian M. Lewis +1
In this contribution to Snowmass 2021, we present benchmark parameters for the general complex scalar singlet model. The complex scalar singlet extension has three massive scalar s…
Good things to do with extra Higgs doublets
Hooman Davoudiasl, Ian M. Lewis, Matthew Sullivan
In this contribution to the Snowmass 2021 process, we outline models with two or three Higgs doublets that address open questions of particle physics and cosmology. In particular,…
The Impact of Dimension-8 SMEFT Contributions: A Case Study
Sally Dawson, Samuel Homiller, Matthew Sullivan
The use of the SMEFT Lagrangian to quantify possible Beyond the Standard Model (BSM) effects is standard in LHC and future collider studies. One of the usual assumptions is to trun…
Exploring Strange Origin of Dirac Neutrino Masses at Hadron Colliders
Hooman Davoudiasl, Ian M. Lewis, Matthew Sullivan
We consider the possibility that Dirac neutrino masses may be a manifestation of chiral symmetry breaking via non-perturbative QCD dynamics. The key role played by light quarks in…
Higgs boson potential at colliders: status and perspectives
B. Di Micco, M. Gouzevitch, J. Mazzitelli +104
This document summarises the current theoretical and experimental status of the di-Higgs boson production searches, and of the direct and indirect constraints on the Higgs boson se…
