Welcome and opening remarks by the president of APCTP
The Electron Ion Collider (EIC) will be built at Brookhaven National Laboratory (BNL) in partnership with Jefferson Laboratory. With its high luminosity, polarized electron and light ion beams and its ability to bring any nucleus from protons to Uranium in collisions with electrons at various center of mass energies, it will arguably be the most versatile and powerful accelerator facility...
An overview of the progress preparing the Electron-Ion Collider (EIC) for construction. The presentation addresses the EIC design requirements, conceptual design, and construction schedule. Current efforts to promote international engagement and collaboration will be described, including opportunities for contributions to the design and construction of the accelerators and collaboration on the...
The electron ion collider (EIC) is the next generation collider that collides electrons with protons and nuclei to study the internal structure of particles and exotic matter with unprecedented precision. Given to be built at Brookhaven National Laboratory, an active discussion is ongoing for developing detectors worldwide. In this presentation, we will report on Korean groups' current status...
I will discuss the partonic structure of the proton and nuclei at an EIC with an emphasis on the gluonic gravitational form factors. Then present the experimental activities of the Argonne medium energy group to address the above science at an EIC. It comprises a proposed barrel imaging electromagnetic calorimeter for the ePIC detector, the development of a polarized Li6 ion beam, the...
The Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) will undergo extensive Phase-2 upgrades during the long shutdown 3 (LS3) scheduled to prepare for the challenging conditions of the High-Luminosity LHC (HL-LHC). One of the most prominent aspects of the upgrade will be the introduction of a new detector sub-system, the MIP Timing Detector (MTD), situated between the...
In this talk, I summarize the efforts of the Korean Physics Community, in particular, in nuclear and hadron physics, to contribute to the EIC project. I review the previous efforts at the beginning period of the EIC project and introduce the activities of the Korean community in the physics of EIC. This includes the introduction to APCTP and its support for the Korean community's efforts for EIC.
Masses and spins of hadrons are fundamental quantities in physics; however, their origins are not understood yet and their investigations are major purposes of building electron-ion colliders for physics in 2030's. Both of them can be investigated by generalized parton distributions (GPDs). The spacelike (timelike) GPDs are studied by deeply virtual Compton scattering (two-photon processes) at...
In the present talk, we review recent work on the gravitational form factors (GFFs) and the energy-momentum tensor (EMT) distributions of the baryon octet. Based on the SU(3) chiral quark-soliton model, we first examine the effects of flavor SU(3) symmetry breaking on the GFFs. We observe that a heavier hyperon is energetically more compact than a lighter one. We also show that the spin...
Electron-Ion Collider (EIC) is one of the most important scientific programs in nuclear and high energy physics disciplines in the coming future. Taiwanese institutions have been deeply involved in both detector developments and physics analyses in many territories, including RHIC, LHC, and other experiments on fixed target physics, heavy-ion physics, and (Beyond) Standard Model physics....
A new inner tracking system (ITS2) with monolithic active silicon pixel sensors has been successfully installed and is operated for the ALICE experiment at Run 3. For further improvement of the inner layers of the tracking system (ITS3), wafer-scale bent pixel sensors are under development based on the flexibility of the silicon sensor of about 30 µm thickness. The wafer-scale sensor can be...
The Electron-Ion Collider (EIC) Project is the next plan for nuclear physics in the United States. It is the first polarized electron-proton and electron-nucleus collider which opens new areas of quantum chromodynamics (QCD) physics and expands the richness of nuclear and hadron physics. Accurate particle identification performance is essential to achieving the physics goals. A compact...
As part of the CMS Phase 2 upgrade, MIP Timing Detector is planned to be installed in order to mitigate the impact of pileup that is expected to reach 200 in HL-LHC. Due to the difference in the radiation environment, different technologies are used for the barrel and the endcap regions. Low Gain Avalanche Diode (LGAD) sensors are used in the endcap region due to their radiation-hardness....
The dual-readout calorimeter (DRC) is one of calorimeter candidates to achieve very high energy resolutions for both EM and hadronic particles in future colliders such as FCC-ee and CEPC. Korea DRC collaboration has studied various aspects of the DRC R&D and performed the test-beam experiment with two prototype modules at CERN in the last August. In this talk, we present the recent progress of...
I will present recent advancements in the field of GPD phenomenology. This includes, but is not limited to, work on a better understanding of model biases spoiling the extraction of GPD information. New elements of impact studies supporting future experimental programmes will be presented as well.
The recent measurements on exclusive backward-angle electroproduction of meson from Jefferson Lab electron-proton fixed-target scattering experiments above the resonance region, hint at a new domain of applicability of QCD factorization in a unique u-channel kinematics regime, known as the nucleon-meson Transition Distribution Amplitude (TDA). Thanks to these pioneering efforts, the interest...
The sPHENIX detector currently under construction at the Relativistic Heavy Ion Collider (RHIC) at BNL will measure a suite of unique jet, open heavy flavor and Upsilon observables with unprecedented statistics and kinematic reach at RHIC energies. A MAPS-based silicon pixel VerTeX detector upgrade to sPHENIX, the MVTX, will provide a precise determination of the impact parameter of tracks...
Korea has a strong industrial backgrounds in the Si device processing, which has been utilized for the ITS upgrade project of the ALICE experiment. ALPIDE is the monolithic active pixel sensor, an advanced form of the Si sensor, for the project. The sensor was fabricated by the advanced Si device processing technology, and Korean involvements in the effort includes a broad spectrum, the...
The proposed new Electron-Ion collider poses a technical and intellectual challenge for the detector design to accommodate the long-term diverse physics goals envisaged by the program; one requires a 4𝝅 detector system capable of identifying and reconstructing the energy and momentum of final state particles with high precision. The EPIC collaboration has formed to design, build, and take data...
ALICE3 is proposed as the next-generation experiment for LHC Run 5 to address unresolved questions that cannot be answered fully with the present or currently planned detectors. Some key measurements will be the precise measurements of heavy-flavour probes, charmed exotic states, high-precision measurements of electromagnetic radiation, and chiral-symmetry restoration. To pursue this physics...
Measurements in semi-inclusive deep inelastic scattering provide a wide range of insights into nucleon structure and hadronization. Spin asymmetries and cross sections in single-hadron and dihadron production are sensitive to various combinations of transverse momentum-dependent (TMD) distribution and fragmentation functions, depending on the polarizations of the initial electron and target...
Nucleon-to-meson Transition Distribution Amplitudes (TDAs) appear as building blocks in the collinear factorized description of amplitudes for a class of hard exclusive reactions prominent examples being hard exclusive pion electroproduction off a nucleon in the backward region and baryon-antibaryon annihilation into pion and a lepton pair. We discuss general properties of nucleon-to-meson...
