High Precision Fundamental Physics Experiments at JLab with Spin-transparent Storage Rings of Low-energy Polarized Electron Beams
Vladimir Khachatryan, Riad Suleiman, Alberto Accardi +27
A breakthrough in fundamental physics experiments measuring particle spin precession may happen if spin-transparent storage rings become adopted tools for such experiments. We pres…
Universal characterization of Efimovian System via Faddeev Techniques
Ghanashyam Meher, Sourav Mondal, Udit Raha
We demonstrate remnant structural universality in a putative S-wave -halo-bound system in the channel by invoking the zero-coupling limit (ZCL), which elim…
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…
A practical approach to perturbative corrections to few-body observables
Sourav Mondal, Martin Schäfer, Mirko Bagnarol +3
We formulate two methods to facilitate the calculation of perturbative corrections to quantum few-body observables. Both techniques are designed for a numerical realization in comb…
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…
