A lucky day for physics at the #LHC 🍀

Earlier today, the Large Hadron Collider reached an integrated luminosity of 100 inverse femtobarns – equivalent to ten million billion collisions – delivered to the @ATLASexperiment and the @CMSExperiment in 2024, with 28 days of proton–proton collisions to go. This is a first-time achievement in a single run of the #LHC.

Luminosity is an important indicator of the performance of an accelerator: it is proportional to the number of collisions that occur in a certain amount of time. The higher the luminosity, the more data the experiments can gather for #physics research.

Do you remember why there is no data referring to the period from 2018 to 2022? Here’s a hint: #LHCRun3

5/ 📊 We use simulations to optimize the beam parameters for C3, enhancing luminosity without increasing the background. We propose a new parameter set, achieving around 40% higher luminosity compared to the baseline scenario while maintaining similar background levels.

[Dimitris Ntounis @dimntounis]

8/ 🤝 More detailed accelerator & detector studies are necessary to fully evaluate the feasibility of C3 but this work is already an important step towards realizing the next generation of particle colliders. We all need to work together to achieve this!

[Dimitris Ntounis @dimntounis]

4/ 🎇 Beamstrahlung, radiation from the intense beam focusing, is a key consideration. We found C3’s beamstrahlung parameters comparable to other colliders, ensuring the effective performance of the detectors without excessive background.

3/ 🔍 Key parameters for C3 include beam sizes focused down to the nanometer size to achieve target luminosities. We discuss how beam-beam interactions impact the achievable instantaneous luminosity and the creation of background particles.

[Dimitris Ntounis @dimntounis]

2/ 🌟 Why C3? High luminosity is key for precision studies of the Higgs boson and other fundamental particles. We show that C3 can achieve collision rates comparable to other proposals but with more manageable beam-induced background fluxes. #HiggsBoson #HiggsFactory
