Energy evolution of T-odd gluon TMDs at small
Daniël Boer, Yoshikazu Hagiwara, Jian Zhou +1
We study the energy or TMD evolution of the three leading twist dipole type T-odd gluon TMDs inside a transversely polarized nucleon, all of which at small dynamically originat…
Coulomb nuclear interference effect in dipion production in ultraperipheral heavy ion collisions
Yoshikazu Hagiwara, Cheng Zhang, Jian Zhou +1
We study exclusive pair production near resonance peak in ultraperipheral heavy ion collisions. Pion pair can either be produced via two photon fusion process or fr…
Spin-dependent Pomeron and Odderon in elastic proton-proton scattering
Yoshikazu Hagiwara, Yoshitaka Hatta, Roman Pasechnik +1
We introduce a new model of near-forward elastic proton-(anti)proton scattering at high energy based on the modern formulation of Pomeron and Odderon in terms of Wilson lines and g…
Computing the gluon Sivers function at small-
Xiaojun Yao, Yoshikazu Hagiwara, Yoshitaka Hatta
We compute the gluon Sivers function of the transversely polarized nucleon at small- by exploiting the known connection between the dipole gluon Si…
Accessing the gluon Wigner distribution in ultraperipheral collisions
Yoshikazu Hagiwara, Yoshitaka Hatta, Roman Pasechnik +2
We propose to constrain the gluon Wigner distribution in the nucleon by studying the exclusive diffractive dijet production process in ultraperipheral proton-nucleus collisions (UP…
