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…
Low-Energy Effective Field Theory of Lepton-Proton Bremsstrahlung
P. Talukdar, F. Myhrer, U. Raha
We calculate the cross section for the lepton-proton bremsstrahlung process in effective field theory. This process corresponds to an undetected background s…
An update of muon capture on hydrogen
S. Pastore, F. Myhrer, K. Kubodera
The successful precision measurement of the rate of muon capture on a proton by the MuCap Collaboration allows for a stringent test of the current theoretical understanding of this…
Neutrino Emissivities from Deuteron-Breakup and Formation in Supernovae
S. Nasu, S. X. Nakamura, K. Sumiyoshi +3
Neutrino emissions from electron/positron capture on the deuteron and the nucleon-nucleon fusion processes in the surface region of a supernova core are studied. These weak process…
The muon capture rate on hydrogen and the values of and
S. Pastore, F. Myhrer, K. Kubodera
Motivated by the recent developments in the determination of the experimental values of the nucleon axial-vector coupling constant and the pion-nucleon coupling constant $g_{…
Pion production in nucleon-nucleon collisions in chiral effective field theory with Delta(1232)-degrees of freedom
A. A. Filin, V. Baru, E. Epelbaum +3
A calculation of the pion-production operator up to next-to-next-to-leading order for s-wave pions is performed within chiral effective field theory. In the previous study [Phys. R…
Ordinary Muon Capture in Hydrogen Reexamined
U. Raha, F. Myhrer, K. Kubodera
The rate of muon capture in a muonic hydrogen atom is calculated in heavy-nucleon chiral perturbation theory up to next-to-next-to leading order. To this order, we present the syst…
Muon Capture on the Deuteron -- The MuSun Experiment
V. A. Andreev, R. M. Carey, V. A. Ganzha +28
We propose to measure the rate \Rd\ for muon capture on the deuteron to better than 1.5% precision. This process is the simplest weak interaction process on a nucleus that can both…
Quark-quark correlations and baryon electroweak observables
H. Hogaasen, K. Kubodera, F. Myhrer
The simple independent quark models have difficulties explaining simultaneously the totality of the known hyperon magnetic moments and hyperon semi-leptonic decay rates. We show th…
The capture rate in effective field theory
S. Ando, T. -S. Park, K. Kubodera +1
Muon capture on the deuteron is studied in heavy baryon chiral perturbation theory (HBChPT). It is found that by far the dominant contribution to capture comes from a region o…
Pion-nucleon scattering and the nucleon sigma term in an extended sigma model
V. Dmitrasinovic, F. Myhrer
A modified linear sigma model that allows for by addition of vector and pseudovector coupling terms was discussed by Bjorken and Nauenberg and by Lee. In this ext…

Radiative Muon Capture by a Proton in Chiral Perturbation Theory
T. Meissner, F. Myhrer, K. Kubodera
The first measurement of the radiative muon capture (RMC) rate on a proton was recently carried out at TRIUMF. The TRIUMF group analyzed the RMC rate in terms of the theoretical fo…
Electromagnetic Decays of Hyperons (II)
Y. Umino, F. Myhrer
Excited negative parity hyperon masses are calculated in a chiral bag model in which the pion and the kaon fields are treated as perturbations. We also calculate the hadronic width…
