Since the initial development of charged particle colliders in the middle of the 20th century,
these advanced scientific instruments have been at the forefront of scientific discoveries in …

The European Particle Physics Strategy Update (EPPSU) process takes a bottom-up
approach, whereby the community is first invited to submit proposals (also called inputs) for …

With centre-of-mass energies covering the Z pole, the WW threshold, the HZ production, and
the top-pair threshold, the FCC-ee offers unprecedented possibilities to measure the …

The electron-positron stage of the Future Circular Collider, FCC-ee, is a frontier factory for
Higgs, top, electroweak, and flavour physics. It is designed to operate in a 100 km circular …

The beam longitudinal dynamics code blond, utilized tool, has been developed at CERN
since 2014. It has emerged as a central tool for conducting longitudinal beam dynamics …

A bstract This paper presents the prospects for a precise measurement of the branching
fraction of the leptonic\({B} _c^{+}\)→ τ+ ν τ decay at the Future Circular Collider (FCC-ee) …

Higgs pair production provides a unique handle for measuring the strength of the Higgs self
interaction and constraining the shape of the Higgs potential. Among the proposed future …

In this letter we present a novel approach for a high-energy high-luminosity electron-positron
collider. Present designs for high-energy electron-positron colliders are either based on two …

We propose a novel method using the ZZ-fusion channel and forward muon detection at
high energy muon colliders to address the challenge of the Higgs coupling-width …

Crystal calorimeters have a long history of pushing the frontier on high-resolution
electromagnetic (EM) calorimetry for photons and electrons. We explore in this paper major …
