Title: Next-to-Leading Power Resummed Rapidity Distributions Near Threshold for Drell-Yan and Diphoton Production...
Title: Optimization of Superconducting Cavities: Shape, Fields, Multipactor
Abstract: A method is discussed to search geometrical parameters of elliptical cavities to obtain the best possible figures of merit: B_pk/E_acc (peak magnetic field) and GR/Q (losses) for a given E_pk/E_acc (peak electric field), aperture, wall slope...
Title: Methods for high-precision determinations of radiative-leptonic decay form factors using lattice QCD
Abstract: In the region of hard photon energies, radiative leptonic decays of pseudoscalar mesons represent important probes of the internal structure of hadrons. Such decays are particularly interesting for heavy...
Quantum Chromodynamics (QCD) is one of the pillars of the Standard Model of particle physics. It describes the strong interaction - one of the four fundamental forces of nature. This force holds quarks and gluons - collectively known as partons - together in hadrons such as the proton, and protons and neutrons together in atomic nuclei. QCD was developed and defined over a brief period from 1972 - 73. One hallmark of QCD is asymptotic freedom, which states that the strong force between quarks and gluons decreases with increasing energy. Asymptotic freedom was discovered in 1973 by David...
Title: Introduction and SCL3 Cryogenic Commissioning (First Run) of Cryogenic Systems for RAON Accelerator
Speaker: Taekyung Ki
Abstract: In South Korea, a heavy ion accelerator (RAON) aims to supply not only rare isotype beams, but also stable heavy ions by using the Isotope Separation On-Line (ISOL), In-flight Fragment (IF) separator, and two Super Conducting Linacs (SCL3 and SCL2...
We invite you to participate in the 14th International Workshop on the Physics of Excited Nucleons. The workshop will take place in beautiful York, UK on June 17-21, 2024. The well-established NSTAR workshop brings together expertise from both experiments and theory to discuss the current progress and future prospects on the physics of the Baryon spectrum and the structure of excited nucleons. Studying the nucleon...
It's like our version of "Shark Tank" - Quark Tank! SLAM is short-talk competition challenging post-doc contestants to present a compelling 3-minute presentation on their research that a non-specialist can understand. The winner will be Jefferson Lab's representative that will compete against contestants from the sixteen other national labs on Capitol Hill in Washington, D.C., on Nov. 15. There, contestants will...
Title: Electron Scattering Off Online-produced Radioactive Isotope - first results from RIKEN SCRIT e-scattering facility
Speaker: Toshimi Suda (Tohoku University, Sendai, Japan)
Abstract: In this seminar, I will present the results of the world's first electron scattering off an online produced radioactive isotope. This achievement was recently accomplished at the RIKEN SCRIT electron-scattering facility in Japan.
The SCRIT facility is designed to probe the internal structures of short-lived exotic nuclei by electron scattering. This facility employs...
