Published in 2018 at "Journal of High Energy Physics"

DOI: 10.1007/jhep10(2018)141

Abstract: A bstractThe pion-pole contribution to hadronic light-by-light scattering in the anomalous magnetic moment of the muon (g − 2)μ is fully determined by the doubly-virtual pion transition form factor. Although this crucial input quantity is,… read more here.

Published in 2019 at "Journal of High Energy Physics"

DOI: 10.1007/jhep10(2019)090

Abstract: Abstract We extract the pion transverse momentum dependent (TMD) parton distribu- tion by fitting the pion-induced Drell-Yan process within the framework of TMD factoriza- tion. The analysis is done at the next-to-next-to-leading order (NNLO) with… read more here.

Published in 2017 at "Journal of High Energy Physics"

DOI: 10.1007/jhep11(2017)203

Abstract: A bstractIt is known that soft photon and graviton theorems can be regarded as the Ward-Takahashi identities of asymptotic symmetries. In this paper, we consider soft theorem for pions, i.e., Nambu-Goldstone bosons associated with a… read more here.

Published in 2021 at "Chinese Physics C"

DOI: 10.1088/1674-1137/abe10e

Abstract: Transport models cannot simultaneously explain very recent data on pion multiplicities and pion charged ratios of Sn+Sn in the reaction at 0.27 A GeV. This stimulates further investigations on the pion dispersion relation, in-medium $N\pi\to… read more here.
