Charged-current cross sections are calculated for quasielastic neutrino and antineutrino scattering using a relativistic meson-nucleon model. We examine how nuclear-structure effects, such as relativistic random-phaseapproximation (RPA) corrections and momentum-dependent nucleon selfenergies, influence the extraction of the axial form factor of the nucleon. RPA corrections are important only at...

Extreme mass ratio bursts (EMRBs) have been proposed as a possible source for future spaceborne gravitational wave detectors, such as the Laser Interferometer Space Antenna (LISA). These events are characterized by long-period, nearly-radial orbits of compact objects around a central massive black hole. The gravitational radiation emitted during such events consists of a short burst, correspond...

We present the first calculation of the h̄-Wigner–Kirkwood corrections to a relativistic system of fermions in the presence of external scalar and vector potentials. The method we propose allows to compute efficiently semiclassical corrections to one body operators such as mean energies and local densities. It also preserves gauge invariance and produces explicitly convergent results despite som...

We compute the next-to-leading order perturbative QCD corrections to the correlators of nucleon interpolating currents in relativistic nuclear matter. The main new result is the calculation of the O(αs) perturbative corrections to the coefficient functions of the vector quark condensate in matter. This condensate appears in matter due to the violation of Lorentz invariance. The NLO perturbative...

It is demonstrated how perturbative O(α2 s ) relativistic corrections to the non-relativistic stable heavy quark-antiquark production cross section in ee annihilation based on a Coulombic QCD potential can be systematically calculated using the concept of effective field theories. The O(αs) corrections from the relativistic energy-momentum relation, the relativistic phase space corrections and ...

We present the first calculation of the }4 Wigner–Kirkwood corrections to a relativistic system of fermions in the presence of external scalar and vector potentials. The method we propose allows the efficient computation of semiclassical corrections to one-body operators such as mean energies and local densities. It also preserves gauge invariance and produces explicitly convergent results desp...

We present a weak-relativistic limit comparison between the Kohn-Sham-Dirac equation and its approximate form containing the exchange coupling, which is used in almost all relativistic codes of density-functional theory. For these two descriptions, an exact expression of the Dirac Green’s function in terms of the nonrelativistic Green’s function is first derived and then used to calculate the e...

Darwin-Foldy nuclear-size corrections in electronic atoms and nuclear radii are discussed from the nuclear-physics perspective. Interpretation of precise isotope-shift measurements is formalism dependent, and care must be exercised in interpreting these results and those obtained from relativistic electron scattering from nuclei. We strongly advocate that the entire nuclear-charge operator be u...
