The Future Circular Collider (FCC-ee) is a proposed next-generation particle physics facility that will enable precision measurements of the Higgs boson and the electroweak sector. Achieving these physics goals requires a highly integrated interaction region, where the Machine–Detector Interface (MDI) must accommodate several detector and accelerator components within a very limited...
High-brightness high intensity photogun based electron sources are important for accelerator applications including injectors, energy recovery linacs, electron cooling, and future particle colliders such as EIC, FCC-ee. At Brookhaven National Laboratory, a series of photoguns - delivering polarized and unpolarized electron beams - have been developed and operated to deliver reliable,...
Future Higgs and electroweak studies at the FCC-ee will require Monte Carlo samples far larger than their already unprecedented datasets, while detector designs are still actively being optimized. Thus, full detector simulation and reconstruction is a critical computational bottleneck. We apply Parnassus, a generative machine-learning-based surrogate that merges simulation and reconstruction...
Dual-readout calorimetry achieves superior energy resolution by simultaneously measuring Cherenkov and scintillation light for event-by-event corrections, making it attractive for future Higgs factories. However, extracting these components via full waveform digitization poses significant data-rate challenges for front-end readout. We present a systematic comparison of machine learning (ML)...
We present the first application of AI agents to the design and optimization of detectors for high-energy physics experiments. Our bi-level optimization framework vertically integrates detector geometry, front-end digitization, and high-level reconstruction parameters within a differentiable, end-to-end simulation. Using a segmented dual-readout crystal electromagnetic calorimeter as a case...
The presentation will cover an estimation of the data rates from the vertex detector. The rates are estimated with GEANT4 simulator and digitization of individual pixels. Realistic data formatting and encoding are also applied. A few selected techniques for reduction of the beam-induced backgrounds are explored.
Superconducting Magnet Division, Brookhaven National Laboratory is designing the final focusing quadrupoles, corrector magnets and compensation solenoids (anti-solenoid and screening solenoids)for FCC-ee Interaction region. This talk discusses MDI challenges from consideration of these magnets and general cryogenic cryostat design. Lack of magnetic septum between nearby beam lines needs...
The Future Circular Collider in its electron–positron mode (FCC-ee) will provide an exceptionally clean environment for heavy-flavour physics at the $Z$ pole, with an expected sample of order $10^{12}$ bottom and charm hadrons. This creates an opportunity to study rare and purely leptonic $B_c^+$ decays, including $B_c^+ \to \tau^+ \nu_\tau$, which are sensitive to the CKM element $|V_{cb}|$,...
