The Low-Mass Stars in Starburst Clusters
If star formation depends strongly on the global properties of the environment in which they form, the slope of the IMF as well as the upper and lower mass cut-offs would be expected to vary significantly between violent starbursts and more quiescent star forming regions. To test this hypothesis we observed the stellar content of the two closest massive star forming regions, 30 Doradus and NGC ...
متن کاملCalculating a leptonic mass spectrum
An elementary formalism is described to generate series of massless radial excitations within a relativistic BS (confinement) model, thus excluding orbital excitations. Coupling the photon to the constituent scalar, a finite self-mass integral results in the lowest order of a. It represents an infinite system of self-consistent equations for an infinite number of leptonic masses. The system can...
متن کاملMass spectrum of pentaquarks
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 Θ baryons, we find that the ground state pentaquark has angular momentum and parity J = 1/2− and a small magnetic moment of 0.382 μN . The decay width is suppressed by the spatial overlap with the decay...
متن کاملA New Hybrid Feature Subset Selection Algorithm for the Analysis of Ovarian Cancer Data Using Laser Mass Spectrum
Introduction: Amajor problem in the treatment of cancer is the lack of an appropriate method for the early diagnosis of the disease. The chemical reaction within an organ may be reflected in the form of proteomic patterns in the serum, sputum, or urine. Laser mass spectrometry is a valuable tool for extracting the proteomic patterns from biological samples. A major challenge in extracting such ...
متن کاملA note on the glueball mass spectrum
A conjectured duality between supergravity and N = ∞ gauge theories gives predictions for the glueball masses as eigenvalues for a supergravity wave equations in a black hole geometry, and describes a physics, most close toa hightemeperature expansion of a lattice QCD. We present an analytical solution for eigenvalues and eigenfunctions, with eigenvalues given by zeroes of a certain well-comput...
