The Large Hadron Collider (LHC) is the most powerful particle physics machine, achieving unprecedented energy levels of 14 TeV. While the LHC discovered the Higgs boson, further investigation is necessary to determine if the 'Standard Model' version is complete. A next-generation 'Higgs factory' that produces a larger number of Higgs bosons is needed for precision studies. LEP3, an upgraded large electron-positron collider, represents a cost-effective solution, able to generate about 500,000 Higgs events in six years using existing infrastructure for under $5 billion.
CERN's Large Hadron Collider (LHC) is history's most powerful particle physics machine, colliding protons at 14 TeV of energy, the highest ever achieved, and discovered the Higgs.
A 'Higgs factory' would allow for more Higgs bosons to be produced than the LHC, enabling precision studies to determine if the 'Standard Model' Higgs is fully understood.
LEP3, an upgraded dual-ring collider, could produce approximately 500,000 Higgs events over six years, costing under $5 billion and utilizing existing infrastructure.
A future circular collider would be an extensive investment, initially focusing on electron-positron collisions and later upgrades for a high-energy hadron collider, but with significant costs involved.
