Radially excited pion: electromagnetic form factor and the box contribution to the muon's

Angel S. Miramontes, K. Raya, A. Bashir +2

We investigate the properties of the radially excited charged pion, with a specific focus on its electromagnetic form factor (EFF) and its box contribution to the hadronic light-by…

Electric, Magnetic and Quadrupole Form Factors and Charge Radii of Vector Mesons: From Light to Heavy Sector in a Contact Interaction

R. J. Hernández-Pinto, L. X. Gutiérrez-Guerrero, M. A. Bedolla +1

We present a detailed survey of electric, magnetic and quadrupole form factors of light and heavy spin-1 vector mesons. It complements our analogous analysis of the electromagnetic…
