Full one-loop radiative corrections to the asymmetry parameter of polarised neutron beta decay
Abstract We present a calculation of full one-loop radiative corrections, including the constant term, to the asymmetry parameter of polarised neutron beta decay. This gives the radiative correction to the axial coupling constant ...

Shape coexistence in odd-mass Au isotopes: Determination of the excitation energy of the lowest intruder state in 179Au
Abstract Phenomenon of the shape coexistence has been investigated in 179 79Au100. This very neutron-deficient isotope, 18 neutrons away from the stable gold isotope 197 79Au118, was studied by a combination ...

Perturbativity and a fourth generation in the MSSM
Abstract We study an extension of the MSSM with a fourth generation of chiral matter. With this extension no value of tan β allows the theory to stay perturbative up to the GUT...

Modification of gravitational anomaly method in Hawking radiation
Abstract We discuss an ambiguity of the derivation of the Hawking radiation through the gravitational anomaly method and propose modifications of this method such that it reproduces the correct thermal fluxes. In this modified gravitational anomaly...

1S0 pairing correlation in symmetric nuclear matter with Debye screening effects
Abstract The 1S0 pairing of symmetric nuclear matter is discussed in the framework of relativistic nuclear theory with Dyson–Schwinger equations (DSEs). The in-medium nucleon and meson propagators are...

B-decay signatures of warped top-condensation
Abstract We point out that the light radion ϕ in a recently proposed Warped Top-Condensation Model (WTCM), can provide distinct signatures in b → s ϕ ...

Magnetic moments of antidecuplet pentaquarks
Abstract We analyze the magnetic moments of the exotic pentaquarks of the flavor antidecuplet in the constituent quark model for the cases in which the ground state is in an orbital L p ...

Isomeric lepton mass matrices and bi-large neutrino mixing
Abstract We show that there exist six parallel textures of the charged lepton and neutrino mass matrices with six vanishing entries, whose phenomenological consequences are exactly the same. These isomeric lepton mass matrices are compatible with...

MHD waves within noncommutative Maxwell theory
Abstract In the presence of a strong uniform magnetic field, we study the influence of space noncommutativity on the electromagnetic waves propagating through a quasi-static homogeneous plasma. In this treatment, we have adopted a physical model...

The local B-polarization of the CMB: A very sensitive probe of cosmic defects
Abstract We present a new and especially powerful signature of cosmic strings and other topological or non-topological defects in the polarization of the cosmic microwave background (CMB). We show that even if defects contribute 1% or less in the...

Gravitinos tunneling from black holes
Abstract Black hole radiation of gravitinos is investigated as the classically forbidden tunneling of spin-3/2 fermions through an event horizon. We calculate directly that all four spin states of the gravitino yield the same emission temperature,...

Atmospheric neutrinos as a probe of CPT violation
Abstract We show that atmospheric neutrinos can provide a sensitive and robust probe of CPT violation (CPTV). We perform realistic event-rate calculations and study the variations of the ratio of total muon to antimuon survival rates with ...

Phase Groups and the Origin of Non-locality for Qubits
Abstract We describe a general framework in which we can precisely compare the structures of quantum-like theories which may initially be formulated in quite different mathematical terms. We then use this framework to compare two theories: quantum...

Photo-induced phenomena in correlated electron system with spinstate degree of freedom
Abstract Photo-induced spin-state change in correlated electron systems is examined theoretically, motivated by the recent pump-probe experiments in perovskite cobaltites. Effective Hamiltonian for the photo-excited state is derived from the...

Investigation of Prompt X-ray Emission in Fission
Abstract Prompt K x-ray production yields in 238U(n,f) have been measured for the first time at fast and intermediate neutron energies using the GEANIE array of germanium detectors at the Los Alamos Neutron Science Center. Results are compared with...

Fragment properties from fission of actinide nuclei induced by 6–10 MeV bremsstrahlungI
Abstract Experiments to investigate the photon-induced fission of actinide nuclei at excitation energies in the vicinity of the fission barrier are carried out at the superconducting Darmstadt linear electron accelerator S-DALINAC. A twin–Frisch-grid...
