Abstract Particle physics has arrived at an important moment of its history. The discovery the Higgs boson completed Standard Model, core theory behind known set elementary particles and fundamental interactions. However, Model leaves questions unanswered, such as nature dark matter, origin matter–antimatter asymmetry in Universe, existence hierarchy neutrino masses. To address these newly discovered boson, high-energy colliders are required. Future generations machines must be versatile,...
A key challenge for a future circular collider (FCC) with centre-of-mass energy of 100 TeV and circumference in the range km is development high-field superconducting accelerator magnets, capable providing 16 T dipolar field quality 50 mm aperture. This paper summarizes strategy actions being undertaken framework FCC Magnet Technology Program Work Package 5 EuroCirCol.
A next step of energy increase hadron colliders beyond the LHC requires high-field superconducting magnets capable providing a dipolar field in range 16 T 50-mm aperture with accelerator quality. These characteristics could meet requirements for an upgrade to twice present beam or 100-TeV center mass future circular collider.

After 10 years of physics at the Large Hadron Collider (LHC), particle landscape has greatly evolved. Today, a staged Future Circular (FCC), consisting luminosity-frontier highest-energy electron–positron collider (FCC-ee) followed by an energy-frontier hadron (FCC-hh), promises most far-reaching program for post-LHC era. FCC-ee will be precision instrument used to study Z, W, Higgs, and top particles, offer unprecedented sensitivity signs new physics. Most infrastructure could reused...
The integrated luminosity, a key figure of merit for any particle-physics collider, is closely linked to the peak luminosity and beam lifetime. instantaneous collider constrained by number boundary conditions, such as available current, maximum beam-beam tune shift with acceptable stability reasonable lifetime (i.e., empirical ``beam-beam limit''), or event pileup in physics detectors. at high-luminosity hadron colliders largely determined particle burn off collisions.

Since the CERN ISR, hadron colliders have defined energy frontier. Noteworthy are conversion of Super Proton Synchrotron (SPS) into a proton-antiproton collider, Tevatron as well abandoned SSC in United States. Hadron likely to determine pace particle-physics progress also during next hundred years. Discoveries at past were essential for establishing so-called Standard Model particle physics. The world's present flagship LHC, including its high-luminosity upgrade HL-LHC, is set operate...
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 projects that it would like see realised in near-term, mid-term and longer-term future. National inputs as well from Laboratories are also an important element of process. All these then reviewed by Preparatory Group (PPG), whose role organize Symposium around submitted ideas prepare discussion on importance merits...
