Exclusive neutral-pion electroproduction (ep → e[superscript ′]p[superscript ′]π[superscript 0]) was measured at Jefferson Lab with a 5.75-GeV electron beam and the CLAS detector. Differential cross sections d[superscript 4]σ/dtdQ[superscript 2]dx[subscript B]dϕ[subscript π] and structure functions σ[subscript T] + εσ[subscript L], σ[subscript TT], and σ[subscript LT] as functions of t were obtained over a wide range of Q[superscript 2] and x[subscript B]. The data are compared with Regge and handbag theoretical calculations. Analyses in both frameworks find that a large dominance of transverse processes is necessary to explain the experimental results. For the Regge analysis it is found that the inclusion of ...
