Forward hadron production in pp collisions at LHC energies from an event generator based on the color glass condensate framework
Hirotsugu Fujii, Tetsufumi Hirano, Kazunori Itakura +2
We investigate inclusive forward single-hadron production in high-energy proton--proton collisions using a CGC-inspired Monte Carlo event generator, MC-CGC. We carried out a system…
Dynamical evolution of critical fluctuations with second-order baryon diffusion coupled to chiral condensate
Azumi Sakai, Koichi Murase, Hirotsugu Fujii +1
We develop a dynamical model to describe critical fluctuations in heavy-ion collisions, incorporating the baryon diffusion current and chiral condensate as dynamical degrees of fre…
Critical behavior of the Schwinger model via gauge-invariant VUMPS
Hirotsugu Fujii, Kohei Fujikura, Yoshio Kikukawa +2
We study the lattice Schwinger model by combining the variational uniform matrix product state (VUMPS) algorithm with a gauge-invariant matrix product ansatz that locally enforces…
Scalar Glueball--Quarkonium Mixing and the Structure of the QCD Vacuum
J. Ellis, H. Fujii, D. Kharzeev
We use Ward identities of broken scale invariance to infer the amount of scalar glueball-- meson mixing from the ratio of quark and gluon condensates in the QCD vacuum. A…
