Predicting the Exclusive Diffractive Electron-Ion Cross Section at small with Machine Learning in Sarre
Jaswant Singh, Tobias Toll
The event generator Sarre has been used extensively for simulations of electron-ion collisions in preparation for the Electron-Ion Collider (EIC). Sarre simulates exclusive d…
The case for an EIC Theory Alliance: Theoretical Challenges of the EIC
Raktim Abir, Igor Akushevich, Tolga Altinoluk +167
We outline the physics opportunities provided by the Electron Ion Collider (EIC). These include the study of the parton structure of the nucleon and nuclei, the onset of gluon satu…
Investigating saturation effects and the virtual pion in leading neutron events at HERA with the dipole model
Arjun Kumar, Tobias Toll
We investigate events with very forward neutrons in collisions at HERA using impact parameter dependent colour dipole models with and without saturation. This is the first stu…
Energy dependence of the proton geometry in exclusive vector meson production
Arjun Kumar, Tobias Toll
The gluon radius of the proton is expected to increase at small gluon momentum fractions , an effect which has hitherto not been considered in the dipole model framework. We inv…
Subnucleon fluctuations in coherent and incoherent ultra-peripheral AA collisions at LHC and RHIC with the Sartre event generator
Tobias Toll
Sartre has been extensively used for describing photon-nuclei processes at the electron-ion collider (EIC) as well as ultra-peripheral collisions (UPC) at LHC and RHIC. Sartre is a…
Investigating the structure of gluon fluctuations in the proton with incoherent diffraction at HERA
Arjun Kumar, Tobias Toll
Impact parameter dependent dipole models are ideal tools for investigating the spatial structure of the proton. We investigate the incoherent cross section in exclusive …
Investigating saturation effects in ultraperipheral collisions at the LHC with the color dipole model
Bharath Sambasivam, Tobias Toll, Thomas Ullrich
We investigate saturation effects in scattering as well as in ultraperipheral A and AA collisions at small with four variants of the impact parameter dependent color di…
Exclusive diffractive vector meson production: A comparison between the dipole model and the leading twist shadowing approach
Shashank Anand, Tobias Toll
With the imminent construction of an electron-ion collider in the USA, both saturation physics and nuclear shadowing physics will be important for the same processes for the first…
The dipole model Monte Carlo generator Sartre 1
Tobias Toll, Thomas Ullrich
We present the Monte Carlo generator Sartre for simulating diffractive exclusive vector meson production and DVCS in electron-proton, electron-ion, and hadron-hadron collisions.
Exclusive diffractive processes in electron-ion collisions
Tobias Toll, Thomas Ullrich
We present a new technique to calculate the cross-section for diffractive vector meson production and DVCS in electron-ion collisions based on the dipole model. The measurement of…
Charm and bottom photoproduction at HERA with MC@NLO
Tobias Toll, Stefano Frixione
We apply the MC@NLO formalism to the production of heavy-quark pairs in pointlike photon-hadron collisions. By combining this result with its analogue relevant to hadron-hadron col…
MC@NLO for Heavy Quarks in Photoproduction
Tobias Toll
An MC@NLO for heavy quarks in photoproduction is presented. This is the first lepton-hadron process to be included into MC@NLO. To construct an MC@NLO process dependent so called M…
