The Electron-Ion Collider (EIC) will be the next major facility to study the smallest building blocks of matter and their interactions. This facility will collide spin-polarized electrons and nuclei, thus providing new opportunities to study the spin structure of nucleons. Given the expected performance of the facility, we simulated polarized electron-proton and electron-Helium 3 collisions...
This talk presents a cutting-edge analysis of the 1-jettiness event shape in deep inelastic scattering (DIS), utilizing Soft-Collinear Effective Theory. The study achieves high precision at N$^3$LL + O($\alpha_s^2$) accuracy, incorporating full fixed-order matching along with nonperturbative corrections. It represents one of the most accurate event-shape predictions in DIS to date and supports...
The structure of quarks inside a nucleon is affected by its polarization. This effects can be investigated throught the extraction of the TMD Sivers distribution from DY, SIDIS measurements.
Sartre is an event-generator based on the color dipole model of deep inelastic scattering (DIS). It employs the Good-Walker mechanism to simulate event-by-event fluctuations, which are key to describing the incoherent cross section, where the target breaks up following the interaction. Sartre has been extensively used to describe photon–nucleus interactions at the Electron-Ion Collider (EIC),...
Two processes contribute to the $ep \rightarrow e' p' \gamma'$ reaction: Deeply Virtual Compton Scattering, where the photon is produced at the proton vertex, and the Bether-Heitler process, where the photon is radiated from the electron. A major hurdle in the extraction of Generalised Form Factors (GPDs) from experiment arises due to the presence of two Inverse problems: a first one for the...
Key measurements at the future Electron-Ion Collider (EIC), including first-of-their-kind studies of kaon structure, require the detection of $\Lambda^0$ at forward angles. We present a feasibility study of $\Lambda^0 \rightarrow n\pi^0$ measurements using a high-granularity Zero Degree Calorimeter to be located about 35 m from the interaction point. We introduce a method to address the...
The SiPM-on-Tile technology was adopted by several calorimetry systems
of ePIC, including the forward and backward hadronic calorimeters (1.5 < η <
3.0), the high granularity insert (3.0 < η < 4.0) and the Zero-Degree Calorime-
ter (ZDC, η > 6.0). We developed a ZDC prototype to validate the design and
evaluate its performance with low-energy particles. Beam tests conducted at
Jefferson...
The Electron-Ion Collider (EIC) is a next-generation facility designed to investigate the gluonic structure of nucleons and nuclei via Deep Inelastic Scattering. The EIC physics program, outlined in the EIC White Paper and Yellow Report, led to the development of the general-purpose ePIC detector. To enhance the scientific reach of the EIC, the community supports the addition of a second...
