Recherches actuelles
Phénoménologie et théorie de la physique hadronique, des énergies modérées à asymptotiques et des processus inclusifs aux processus exclusifs. Saturation gluonique à haute énergie et physique au-delà du twist dominant.
J'étudie des aspects théoriques variés de la chromodynamique quantique dans le cadre de la physique des collisionneurs (LHC, futur EIC). Je m'intéresse à la physique de précision (corrections perturbatives) avec eets de saturation gluonique pour les processus exclusifs, et à la tomographie partonique des hadrons via les distributions de parton généralisées aux énergies plus modérées. J'ai prouvé une correspondance exacte entre les descriptions mathématiques du régime de saturation et les distributions de parton audel à du twist dominant, dont j'étudie toujours les conséquences théoriques et phénoménologiques. Cette correspondance permet par exemple de mieux comprendre la physique du spin aux hautes énergies, et de distinguer expérimentalement les diérents eets de diusion multiple en régime saturé.
