Precise Determination of the Proton's Gluon Cloud Geometry from HERA data
Tobias Toll, Nahid Vasim
The paper extracts a precise shape of the proton’s gluon distribution by fitting a hotspot model to exclusive J/ψ production data from HERA, finding a small Gaussian core and a lar…

Efficient calculation of exclusive diffractive cross sections at the EIC and LHeC with the Sartre event generator
Tobias Toll, Dipan Ghosh, Abhinav Srivastav
We present a new version of the Sartre event generator for exclusive diffraction at small xP in the colour dipole model, for and A scattering at the EIC and the LHeC as wel…

Describing UPC Data with the Sarre Event Generator
Vaidehi Nattoja, Tobias Toll
Ultra-peripheral heavy-ion collisions (UPCs) provide a distinct environment for high-energy QCD research, focusing on the production of vector mesons. This proceeding details recen…
