The Electron-Ion Collider in China (EicC) will be constructed based on the upgrade of the High Intensity Heavy-ion Accelerator Facility (HIAF), which is now under construction in Huizhou of Guangdong. The Collider will provide a large integrated experimental platform for research on nuclear and particle physics and related scientific fields. Electron-nucleon scattering is an ideal tool to...
The Beijing Electron Positron Collider II (BEPCII) has achieved a series of achievements in high energy physics study. Along with the deepening of the research, more important physcis is expected in higher energy region (>2.1GeV). As the upper limit of BEPCII design energy is 2.1 GeV, an urgent upgrade is required. In this paper, the upgrade project of BEPCII (BEPCII-U) will be introduced.
The Solenoidal Large Intensity Device (SoLID) is a forward-scattering spectrometer located in Hall-A at Jefferson Lab. With its large acceptance and full azimuthal angular coverage, SoLID is capable of handling high luminosities ranging from 1037 to 1039 /cm2/s, using both polarized and unpolarized targets. The detector makes use of the full potential of the JLab 12 GeV upgrade and is designed...
The Multi-Purpose Detector (MPD) is the flagship experiment in the Nuclotron-based Ion Collider fAcility (NICA) currently under construction at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia. The experiment is designed to run in the collider mode. The MPD will study heavy-ion collisions in the energy range √sNN = 4-11 GeV, starting with Bi+Bi collisions at √sNN = 9.2 GeV. Its...
The LHCb spectrometer has the unique capability to function as a fixed-target experiment by injecting gas into the LHC beampipe while proton or ion beams are circulating. The resulting beam-gas collisions cover an unexplored energy range that is above previous fixed-target experiments, but below the RHIC or LHC collider energies. Here we present recent results on open charm, $J/\psi$, and...
The high-intensity beams provided by the CERN SPS in a wide energy interval offer a unique opportunity to investigate the region of the QCD phase diagram at high baryochemical potential. The fixed-target NA60+ experiment, proposed for taking data with Pb-Pb and p-A collisions at the SPS from 2029, aims at measurements of rare probes of the Quark-Gluon Plasma (QGP) in a beam-energy scan, in the...
An electric dipole aligned along the spin axis of a fundamental particle, nucleus, or atomic system violates both parity conservation and time reversal invariance. The observation of such a phenomenon would, at present or proposed levels of experimental sensitivity, signal new physics beyond the Standard Model.
The usual method for identifying an electric dipole moment (EDM) in such...
Magnetic and electric dipole moments of fundamental particles provide powerful probes for physics within and beyond the Standard Model. For the case of charm baryons these have not been experimentally accessible to date due to the difficulties imposed by their short lifetimes. An experimental test at the insertion region 3 of LHC is foreseen during Run3 to demonstrate the feasibility of a...
Decays of the neutral and long-lived η and η′ mesons provide a unique, flavor-conserving laboratory to test low-energy Quantum Chromodynamics and search for new physics beyond the Standard Model. The program will be realized with the Jefferson Lab Eta Factory (JEF), scheduled to run in 2024 in Hall D at Jefferson Lab. The experiment will use the GlueX apparatus with an upgraded Forward...
A high-intensity GeV gamma beam line, LEPS2, was constructed at SPring-8 in Japan in 2013. A large acceptance solenoidal spectrometer has been constructed to detect charged particles, neutrons, and photons. Since 2021, physics data has been collected in order to study kaonic nuclei, and exotic hadrons. Photoproduction of hyperon resonances and mesons has been successfully observed. In this...
I will discuss the physics cases and opportunities of a future high energy Muon Collider from a Beyond the Standard Model (BSM) perspective.
I will do so by clarifying the role of precision measuements in the search for BSM physics and the role of the BSM parametrization in precision measurements, and reviewing recent studies of the performance of a high energy Muon Collider for precision...
A polarized gaseous target, operated in combination with the high-energy, high-intensity LHC beams and a highly performing LHC particle detector, has the potential to open new physics frontiers and to deepen our understanding of the intricacies of the strong interaction in the non-perturbative regime of QCD. Specifically, the LHCspin project aims to perform spin physics studies in high-energy...
The exploration of the full physics potential of the CEBAF 12 GeV would uniquely benefit from polarized and unpolarized positron beams with quality and modes of operation similar to those of the polarized electron beam. The Jefferson Lab (JLab) Positron Working Group, formed in 2018 and now with over 250 members from 75 institutions, continues to build out a case to support this cause, and has...
The proposed STCF is a symmetric electron-positron beam collider designed to provide e+e− interactions at a center-of-mass energy from 2.0 to 7.0 GeV. The peaking luminosity is expected to be 0.5×1035 cm−2s−1. STCF is expected to deliver more than 1 ab−1 of integrated luminosity per year. The huge samples could be used to make precision measurements...
The future of high energy physics relies on the capability of exploring a broader energy range than current accelerators, with higher statistics. A muon collider combines the great precision of electron-positron machines, with a low level of beamstrahlung and synchrotron radiation, and the high center-of-mass energy and luminosity of hadron colliders.
For these reasons, studies aimed at...
The J-PARC Hadron Experimental Facility was constructed with an aim to explore the origin and evolution of matter in the universe through the experiments with intense particle beams. In the past decade, many results on particle and nuclear physics have been obtained at the present facility. To expand the physics programs to unexplored regions never achieved, the extension project of the Hadron...
The ePIC detector is being designed as a general-purpose detector for the Electron-Ion Collider (EIC) to deliver the full physics program. One of the key challenges at the EIC is particle identification (PID), which requires excellent separation of pions, kaons, and protons over a wide phase space with significant pion/electron suppression. To address this challenge, ePIC utilises multiple...
The ePIC general purpose detector for the Electron-Ion Collider (EIC) will be constructed at the Brookhaven National Laboratory in the US by 2030. It will provide an almost hermetic coverage in tracking, electromagnetic and hadronic calorimetry, as well as particle identification (PID) in the pseudorapidity range between -3.5 and +3.5. In particular, the ePIC backward endcap will be equipped...
