The cosmological constant is probably zero, and a proof is possibly right
Abstract Hawking proposed that the cosmological constant is probably zero in quantum cosmology. Duff claimed that Hawking's proof is invalidated. Using the right configuration for the wave function of the universe, we provide a complete proof. ...

New Structured Scintillators for Neutron Radiography
Abstract We report on the development of novel neutron scintillators fabricated in microcolumnar formats using the physical vapour deposition (PVD) method. Such structures mitigate the conventional trade-off between spatial resolution and detection...

Singlet axial-vector coupling constant of the nucleon in QCD without instantons
Abstract We have analyzed axial-vector current–current correlation functions between one-nucleon states to calculate the singlet axial-vector coupling constant of the nucleon. The octet–octet and the octet–singlet current correlators, investigated...

Intrinsic uncertainty on the nature of dark energy
Abstract We argue that there is an intrinsic noise on measurements of the equation of state parameter w = p/ρ from large-scale structure around us. The presence of the large-scale structure leads to an ambiguity in the definition of the background...

Complex amplitude phase motion in Dalitz plot heavy meson three body decay
Abstract We propose a method to determine the phase motion of a complex amplitude in three body heavy meson decays. We show that the phase variation of a complex amplitude can be directly revealed through the interference observed in the Dalitz plot ...

The neutron charge form factor and target analyzing powers from 3He(e→,e′n) scattering
Abstract The charge form factor of the neutron has been determined from asymmetries measured in quasi-elastic 3 He ( ...

Constructing warm inflationary model in brane–antibrane system
Abstract Recently, various observational data predicted a possibility that inflation may naturally occur in a warm region. In this scenario, radiation is produced during the inflation epoch and reheating is avoided. The main question arises as to...

Ultraviolet fixed point and massive composite particles in TeV scales
Abstract We present a further study of the dynamics of high-dimension fermion operators attributed to the theoretical inconsistency of the fundamental cutoff (quantum gravity) and the parity-violating gauge symmetry of the standard model. Studying...

Accurate renormalization group analyses in neutrino sector
Abstract We investigate accurate renormalization group analyses in neutrino sector between ν-oscillation and seesaw energy scales. We consider decoupling effects of top quark and Higgs boson on the renormalization group equations of light neutrino...

Perturbative and nonperturbative renormalization of anomalous quark triangles
Abstract Anomalous quark triangles with one axial and two vector currents are studied in special kinematics when one of the vector currents carries a soft momentum. According to the Adler–Bardeen theorem the anomalous longitudinal part of the...
