The International Linear Collider (ILC) is on the table now as a new global energy-frontier accelerator laboratory taking data in 2030s. ILC addresses key questions for our current understanding of particle physics. It based proven technology. Its experiments will challenge Standard Model physics and provide window to look beyond it. This document brings story up date, emphasizing its strong motivation, readiness construction, opportunity it presents US community.
A New QCD facility at the M2 beam line of CERN SPS COMPASS++/AMBER
The CALICE Semi-Digital Hadronic Calorimeter (SDHCAL) prototype, built in 2011, was exposed to beams of hadrons, electrons and muons two short periods 2012 on different beam lines the CERN SPS. prototype with its 48 active layers, made Glass Resistive Plate Chambers their embedded readout electronics, run triggerless power-pulsing mode. performance SDHCAL during test found be very satisfactory an efficiency exceeding 90% for almost all layers. A linear response (within 5%) a good energy...
The COMPASS experiment recently discovered a new isovector resonance-like signal with axial-vector quantum numbers, the $a_1(1420)$, decaying to $f_0(980)\pi$. With mass too close and width smaller than ground state $a_1(1260)$, it was immediately interpreted as light exotic meson, similar $X$, $Y$, $Z$ states in hidden-charm sector. We show that fully matching experimental data is produced by decay of $a_1(1260)$ resonance into $K^\ast(\to K\pi)\bar{K}$ subsequent rescattering through...
In this paper we review the physics opportunities at linear $e^+e^-$ colliders with a special focus on high centre-of-mass energies and beam polarisation, take fresh look various accelerator technologies available or under development and, for first time, discuss how facility equipped technology mature today could be upgraded of tomorrow to reach much higher and/or luminosities. addition, will detectors alternative collider modes, as well beyond-collider experiments R\&D facilities part...
We study the spin-exotic $J^{PC} = 1^{-+}$ amplitude in single-diffractive dissociation of 190 GeV$/c$ pions into $\pi^-\pi^-\pi^+$ using a hydrogen target and confirm $\pi_1(1600) \to \rho(770) \pi$ amplitude, which interferes with nonresonant $1^{-+}$ amplitude. demonstrate that conflicting conclusions from previous studies on these amplitudes can be attributed to different analysis models treatment dependence squared four-momentum transfer we thus reconcile their experimental findings....
The high granularity of the CALICE Semi-Digital Hadronic CALorimeter (SDHCAL) provides capability to reveal track segments present in hadronic showers. These are then used as a tool probe behaviour active layers situ, better reconstruct energy these showers and also distinguish them from electromagnetic ones. In addition, comparison data simulation helps discriminate among different shower models simulation. To extract recorded SDHCAL, Hough Transform is after being adapted presence dense...

Based on the observation of sizeable target-transverse-spin asymmetries in single-hadron and hadron-pair production Semi-Inclusive measurements Deep Inelastic Scattering (SIDIS), chiral-odd transversity quark distribution functions $h_1^q$ are nowadays well established. Several possible channels to access these were originally proposed. One candidate is measurement polarisation $\Lambda$ hyperons produced SIDIS off transversely polarised nucleons, where transverse struck might be transferred...
