The development of a TeV-scale muon accelerator and storage ring provides enormous scientific potential not only for a $\mu^+\mu^-$ collider, but also for deep inelastic scattering in a completely new regime when a TeV muon beam is collided with a hadron beam. For example, if the approved Electron-Ion Collider at BNL were eventually upgraded with a TeV muon beam replacing its low energy...

Many astrophysical observations as well as anomalies in processes involving electromagnetic currents (e.g. the muon anomalous magnetic moment) could be reconciled assuming the existence of a new kind of matter, not directly interacting with light, called Dark Matter (DM). While
gravitational effects of DM are quite well established, despite the tremendous efforts being devoted to reveal the...

Initial state radiation is included in the framework. The fitting is...
Low-energy nuclear structure physics continues to be a vibrant field of research, as ever more capable rare isotope facilities look for new elements further away from stability. At these dedicated facilities, short-lived nuclei decay in flight between the production and detection points, making those with shorter decay times difficult to study. The future EIC, however, will have heavy ion...

The...
Exclusive and diffractive final states will provide a wealth of physics at the future Electron-Ion Collider (EIC). However, measurement of these final states provide a unique challenge for detector design since many of the final-state particles wind up at very large pseudorapidities ($\eta$ > 4.5), which is far beyond the acceptance of the central detector. These so-called “far-forward”...

In testing the Standard Model or searching for beyond-the-Standard Model (BSM) physics, many experiments focus on the measurement of the weak mixing angle. The weak mixing angle is the parameter that unifies the electromagnetic and weak interactions, but only in the SM framework.
