Feasibility studies of the time-like proton electromagnetic form factor measurements with PANDA at FAIR
The possibility of measuring the proton electromagnetic form factors in the time-like region at FAIR with the PANDA detector is discussed. Detailed simulations on signal efficiency for the annihilation of p̄+ p into a lepton pair as well as for the most important background channels have been performed. It is shown that precision measurements of the differential cross section of the reaction p̄+ ...
متن کاملFeasibility studies of time-like proton electromagnetic form factors at PANDA at FAIR
Simulation results for future measurements of electromagnetic proton form factors at PANDA (FAIR) within the PandaRoot software framework are reported. The statistical precision with which the proton form factors can be determined is estimated. The signal channel p̄p → e+e− is studied on the basis of two different but consistent procedures. The suppression of the main background channel, i.e. p̄p...
متن کاملMeasurements of the electromagnetic form factor of the Proton at JLab
The ratio of the proton’s elastic electromagnetic form factors GEp/GMp was obtained by measuring Pt and Pl, the transverse and longitudinal recoil proton polarization, respectively. For the elastic reaction ~ep → e~ p, GEp/GMp is proportional to Pt/Pl. The simultaneous measurement of Pt and Pl in a polarimeter reduces systematic uncertainties. The results for the ratio GEp/GMp measured in Hall ...
متن کاملElectromagnetic pion form factor at finite temperature
The electromagnetic form factor of the pion in the space-like region, and at finite temperature, Fπ(Q 2, T ), is obtained from a QCD Finite Energy Sum Rule. The form factor decreases with increasing T, and vanishes at some critical temperature, where the pion radius diverges. This divergence may be interpreted as a signal for quark deconfinement. John Simon Guggenheim Fellow 1994-1995 The possi...
متن کاملPion electromagnetic form factor at finite temperature.
Temperature effects on the electromagnetic couplings of pions in hot hadronic matter are studied with an effective chiral Lagrangian. We show that the Ward-Takahashi identity is satisfied at non-zero temperature in the soft pion limit. The in-medium electromagnetic form factor of the pion is obtained in the time-like region and shown to be reduced in magnitude, especially near the vector-meson ...
