Published inPOS Proceedings of Science
We calculate the small-x evolution of protons with finite size by solving numerically the JIMWLK evolution equation. The initial condition is constrained by the HERA measurements of charm reduced cross section and of exclusive vector meson production. We compute the energy dependence of diffractive cross sections in order to access the energy evolution of the event-by-event fluctuating proton density profile. The fundamental problems arising from the regime sensitive to non-perturbatively large dipoles are also discussed.

Mäntysaari, Heikki; Schenke, Björn (American Physical Society, 2018)The small-x evolution of protons is determined from numerical solutions of the JIMWLK equations, starting from an initial condition at moderate x for a finite size proton. The resulting dipole amplitude is used to calculate ...

Lappi, Tuomas; Ramnath, Andrecia; Rummukainen, K.; Weigert, H. (American Physical Society, 2016)We study the effects of a parity-odd “odderon” correlation in Jalilian-Marian–Iancu–McLerran– Weigert–Leonidov–Kovner renormalization group evolution at high energy. Firstly we show that in the eikonal picture where the ...

Fight evolution with evolution: plasmid-dependent phages with a wide host range prevent the spread of antibiotic resistances Ojala, Ville; Laitalainen, Jarkko; Jalasvuori, Matti (Wiley-Blackwell, 2013)The emergence of pathogenic bacteria resistant to multiple antibiotics is a serious worldwide public health concern. Whenever antibiotics are applied, the genes encoding for antibiotic resistance are selected for within ...
