Gluonic nucleon energy correlators and fracture functions for Color Glass Condensate
Heikki Mäntysaari, Yu Shi, Yossathorn Tawabutr +1
Nucleon energy correlators (NECs) and fracture functions provide novel tools for probing nucleon and nuclear structure at small through measurements in the target fragmentation…
Next-to-leading order evolution of structure functions without PDFs
Tuomas Lappi, Heikki Mäntysaari, Hannu Paukkunen +1
We formulate and numerically solve the Dokshitzer-Gribov-Lipatov-Altarelli-Parisi~(DGLAP) evolution equations at next-to-leading order in perturbation theory directly for a basis o…
Heavy flavor angular correlations as a direct probe of the glasma
Dana Avramescu, Vincenzo Greco, Tuomas Lappi +2
We use classical equations of motion for heavy quarks to show that the pre-equilibrium glasma phase of a heavy ion collision has an extremely strong effect on heavy quark angular c…
The impact of glasma on heavy flavor azimuthal correlations and spectra
Dana Avramescu, Vincenzo Greco, Tuomas Lappi +2
We study the phenomenological impact of the pre-equilibrium glasma initial stage of heavy-ion collisions on heavy quark azimuthal correlations and spectra. Using our numerical solv…
Finite-size effects on small- evolution and saturation in proton and nuclear targets
Heikki Mäntysaari, Jani Penttala, Farid Salazar +1
Within the Color Glass Condensate effective field theory, we assess the importance of including a finite size for the target on observables sensitive to small- evolution. To thi…
Stronger -odd color charge correlations in the proton at higher energy
Adrian Dumitru, Heikki Mäntysaari, Risto Paatelainen
The non-forward eikonal scattering matrix for dipole-proton scattering at high energy obtains an imaginary part due to a -odd three gluon exchange. We present numerical estimate…
