Generalized transverse momentum distributions at small-
Sanjin Benić, Yoshikazu Hagiwara, Boris Šarić +1
We compute the complete set of the leading-twist gluon and sea-quark generalized transverse momentum distributions (GTMDs) in the small-, or eikonal, approximation at vanishing…
Understanding Gravitational Form Factors with the Weizsäcker-Williams Method
Yoshikazu Hagiwara, Xuan-Bo Tong, Bo-Wen Xiao
Understanding the internal structure of nucleons and nuclei has been a topic of enduring interest in high-energy physics. Gravitational form factors (GFFs) provide an important por…
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…
Probing the gluon tomography in photoproduction of di-pions
Yoshikazu Hagiwara, Cheng Zhang, Jian Zhou +1
A sizable azimuthal asymmetry in exclusive di-pion production near resonance peak in ultraperipheral heavy ion collisions recently has been reported by STAR collabo…
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…

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…
Classical and quantum entropy of parton distributions
Yoshikazu Hagiwara, Yoshitaka Hatta, Bo-Wen Xiao +1
We introduce the semiclassical Wehrl entropy for the nucleon as a measure of complexity of the multiparton configuration in phase space. This gives a new perspective on the nucleon…
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…
Elliptic Flow in Small Systems due to Elliptic Gluon Distributions?
Yoshikazu Hagiwara, Yoshitaka Hatta, Bo-Wen Xiao +1
We investigate the contributions from the so-called elliptic gluon Wigner distributions to the rapidity and azimuthal correlations of particles produced in high energy collisi…
Wigner, Husimi and GTMD distributions in the Color Glass Condensate
Yoshikazu Hagiwara, Yoshitaka Hatta, Takahiro Ueda
We study the phase space distributions of gluons inside a nucleon/nucleus in the small- regime including the gluon saturation effect. This can be done by using the relation betw…
Husimi distribution for nucleon tomography
Yoshitaka Hatta, Yoshikazu Hagiwara
We define the QCD Husimi distribution as the phase space distribution of partons inside the nucleon. Compared to the more well-known Wigner distribution, the Husimi distribution is…
Hemisphere jet mass distribution at finite
Yoshikazu Hagiwara, Yoshitaka Hatta, Takahiro Ueda
We perform the leading logarithmic resummation of nonglobal logarithms for the single-hemisphere jet mass distribution in annihilation including the finite- correctio…
Use of the Husimi distribution for nucleon tomography
Yoshikazu Hagiwara, Yoshitaka Hatta
In the context of nucleon structure, the Wigner distribution has been commonly used to visualize the phase-space distribution of quarks and gluons inside the nucleon. However, the…
