Neutrino mass spectrum and lepton mixing [PDF]
, 2000 The program of reconstruction of the neutrino mass and flavor spectrum is outlined and the present status of research is summarized. We describe the role of future solar and atmospheric neutrino experiments, detection of the Galactic supernovae and ...

On the hadronic mass spectrum [PDF]
Il Nuovo Cimento A Series 10, 1967 We argue that the sole requirement of a self-consistent bootstrap including all hadrons up to infinite mass leads to asymptotically exponential laws for the hadron mass spectrum, for momentum distributions, and for form factors (and to a highest temperature).

A MASS FORMULA FOR THE BARYON MASS SPECTRUM [PDF]
, 1965 A mass spectrum of the form m~ = M 2 = M l (M 1 + | al |) is derived, where a l is the imaginary part of the l th singularity in the complex energy plane of a T-matrix which describes the interaction of a particle of initial rest mass m with a potential V(x, t), where V(x, t) = 0 in the limit |t| -> oo.

Mass Spectrum of a Starburst [PDF]
Symposium - International Astronomical Union, 2004 The fragmentation of supershells and filaments driven by a superwind in a starburst region produces clumps with a mass spectrum approximated by a power law. Its spectral index is close to −2.3. We present results of computer simulations using the thin shell approximation, which are compared to 3D hydrodynamical simulations with self-gravity using the ...

Particle production in time-dependent gravitational fields: the expanding mass shell [PDF]
, 2002 We compute the production of particles from the gravitational field of an expanding mass shell. Contrary to the situation of Hawking radiation and the production of cosmological perturbations during cosmological inflation, the example of an expanding ...

The spectrum of massive excitations of 3d 3-state Potts model and universality [PDF]
, 2006 We consider the mass spectrum of the 3$d$ 3-state Potts model in the broken phase (a) near the second order Ising critical point in the temperature - magnetic field plane and (b) near the weakly first order transition point at zero magnetic field. In the

New sialic acid-containing sulfolipid: “ungulic acid”
Journal of Lipid Research, 1969 Human epidermis, hair, nails, and kidney as well as bovine and horses' hooves were found to contain a lipid fraction, which on thin-layer chromatography migrated slightly ahead of the cerebroside sulfate esters and gave the color reaction specific for ...

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 Mass-spectrum of Iron [PDF]
Nature, 1922 I HAVE recently investigated this element by using the vapour of its penta-carbonyl mixed with carbon dioxide. It is even more troublesome to deal with than the corresponding nickel compound, but by employing intense discharges and long exposures fairly satisfactory results have been obtained.
