We will describe progress along simulation based inference in the precision era.
The progress of control system till OCt. 2026 will be introduced. Especially the progress of the accelerator data acquisition of the intellectual upgrade project of BEPCII will be introduced.
If the SM-like Higgs boson is realized as a mixture of scalar and pseudoscalar states, the CP violating mixing angle can be measured through various Higgs boson production and decay channels. Here we consider Higgs to tau-pair decays, at 240 GeV CEPC with 5.6 ab-1 of simulated data. Preliminary projections of the absolute uncertainty of the mixing angle are given, for the Higgs boson...
Aerogel is unique material with refractive index between gaseous and liquids. Due to this circumstance highly transparent aerogels are good candidates for Cherenkov radiators in RICH detectors. There are several HEP projects required excellent PID performance in the world. For some of them RICH detectors based on aerogel produced in Novosibirsk were proposed by BINP team. Among them FARICH...
This work presents the design and analytical optimization of a high-power, high-efficiency S-band multi-beam klystron (MBK) intended as an RF power source for large-scale scientific facilities. Existing accelerator klystrons demonstrate $50-80 MW$-class peak power near $2.856 GHz$, whereas established MBKs and recent high-efficiency developments operate in the $60-70\%$ electronic-efficiency...
Higher-order contributions due to initial state radiation (ISR) in electron-positron annihilation processes are analyzed analytically and numerically. Effects due to variation of factorization scale and scheme choices in ISR are studied. A new procedure for exponentiation of higher-order next-to-leading photonic and pair corrections is suggested. The results are relevant for increasing the...
We present recent updates to the ReneSANCe Monte Carlo event generator.
ReneSANCe provides one-loop EW and higher order corrections for the processes
$e^+e^- \to HZ$, $e^+e^- \to ZZ$, $e^+e^- \to \gamma Z$ and processes used for luminosity monitoring.
We have taken the first steps to enable decays of final state unstable particles and radiative corrections in decays. All spin correlations...
We give a report on new developments in the gamma-gamma collision mode of the ReneSANCe Monte Carlo event generator. Results for a number of polarized Standard Model processes will be presented for future gamma-gamma colliders based on ee-colliders where high energy photons are produced via Compton backscattering of laser beams.
Quantum-information observables offer new tools for probing collider events beyond traditional quantities such as cross sections and invariant masses. This work investigates quantum entanglement in top–antitop pairs produced via e⁺e⁻ → tt̄, using spin density matrices generated with the recently developed Density Mode framework within MadGraph5_aMC@NLO. Events were simulated at leading order...
Long scintillation strips with embedded WLS fibers are widely used in muon systems of modern experimental facilities, including future electron-positron colliders. To accurately reconstruct particle tracks and to simulate the passage of particles through the strips of the muon system, it is necessary to know the parameters of the scintillators with high accuracy: light output, attenuation...
