Elastic lepton-proton two-photon exchange scattering: An exact HBPT analysis including hadronic effects at NNLO
Rakshanda Goswami, Pulak Talukdar, Bhoomika Das +2
We present an exact analytical evaluation of the two-photon exchange (TPE) correction to the elastic lepton-proton differential scattering cross section at low-energies within the…
Chiral enhancement in soft-photon bremsstrahlung and charge asymmetry in low-energy lepton-proton scattering
Bhoomika Das, Rakshanda Goswami, Pulak Talukdar +2
We carry out a Lorentz gauge evaluation of the single-soft photon bremsstrahlung radiative corrections to the unpolarized elastic lepton-proton scattering cross section at low ener…
Lepton-proton two-photon exchange with improved soft-photon approximation including proton's structure effects in HBPT
Rakshanda Goswami, Pulak Talukdar, Bhoomika Das +2
We present an improved evaluation of the two-photon exchange correction to the unpolarized lepton-proton elastic scattering process at very low-energies relevant to the MUSE experi…
Scale-(in)dependence in quantum 4-body scattering
Sourav Mondal, Rakshanda Goswami, Udit Raha +1
We investigate the multi-channel 4-body scattering system using regularized 2- and 3-body contact interactions. The analysis determines the sensitivity of bound-state energies, sca…
