N* Mass Spectrum from an Anisotropic Action [PDF]

, 2000
Results are reported for N* masses in the 1/2+ and 1/2- sectors on an anisotropic lattice. The gauge action is the usual plaquette plus rectangle type, the quark action is of the D234 type, both having tadpole-improved tree-level coefficients.

Analysis of hadronic invariant mass spectrum in inclusive charmless semileptonic B decays [PDF]

, 1998
We make an analysis of the hadronic invariant mass spectrum in inclusive charmless semileptonic B meson decays in a QCD-based approach. The decay width is studied as a function of the invariant mass cut.

Mass spectrum of pentaquarks

, 2004
We discuss the properties of the pentaquark in a collective stringlike model with a nonplanar configuration of the four quarks and the antiquark. In an application to the mass spectrum of exotic Theta baryons, we find that the ground state pentaquark has angular momentum and parity J(p)=1/2(-) and a small magnetic moment of 0.382 nuclear magnetons.

Asymmetrical braneworlds and the charged lepton mass spectrum

Physics Letters B, 2023
A braneworld mechanism for explaining the mass spectrum of the charged leptons is proposed. Based on the existence of an asymmetric warp factor for a 5+1-dim braneworld scenario, the proper fractions between the masses of the electron, muon and tauon are

V_{ub} from the Hadronic Invariant Mass Spectrum in Semileptonic B Decay [PDF]

, 1997
The hadronic invariant mass spectrum for the inclusive charmless semileptonic decay $B\to X_u e \bar\nu_e$ is studied.

The Apoptosis Regulator 14-3-3η and Its Potential as a Therapeutic Target in Pituitary Oncocytoma

Frontiers in Endocrinology, 2019
The 14-3-3 protein family has attracted much attention in research into the pathogenesis of human tumors because of its involvement in tumorigenesis. In previous studies, we found that 14-3-3η was highly expressed in pituitary oncocytoma.

ppbar enhancement in B and J/Psi decay

, 2006
The near-threshold enhancement in the ppbar invariant mass spectrum from the B^+ -> K^+ ppbar decay reported recently by the BaBar Collaboration is studied within the J\"ulich NNbar model.

Covariance of the One-Dimensional Mass Power Spectrum [PDF]

, 2004
We analyse the covariance of the one-dimensional mass power spectrum along lines of sight. The covariance reveals the correlation between different modes of fluctuations in the cosmic density field and gives the sample variance error for measurements of ...

The Perils of Clumpfind: The Mass Spectrum of Sub-structures in Molecular Clouds [PDF]

, 2009
We study the mass spectrum of sub-structures in the Perseus Molecular Cloud Complex traced by 13CO (1-0), finding that $dN/dM\propto M^{-2.4}$ for the standard Clumpfind parameters.
