Signatures of Spontaneous Breaking of R-Parity in Gluino Cascade Decays at LHC
A. Bartl, W. Porod, F. de Campos +4
We study the pattern of gluino cascade decays in a class of supersymmetric models where R-parity is spontaneously broken. We give a detailed discussion of the R-parity violating de…
Characterization of Solidified Gas Thin Film Targets via Alpha Particle Energy Loss
MUH collaboration, M. C. Fujiwara, G. A. Beer +15
A method is reported for measuring the thickness and uniformity of thin films of solidified gas targets. The energy of alpha particles traversing the film is measured and the energ…
Spinless Salpeter Equation: Laguerre Bounds on Energy Levels
Wolfgang Lucha, Franz F. Schöberl
The spinless Salpeter equation may be considered either as a standard approximation to the Bethe--Salpeter formalism, designed for the description of bound states within a relativi…
Impact of squark pair decay modes on search for supersymmetric neutral Higgs bosons
Alfred Bartl, Helmut Eberl, Keisho Hidaka +3
We present a detailed study of the decays of the neutral Higgs bosons and within the Minimal Supersymmetric Standard Model. We find that the supersymmetric modes ${\til…
Relativistic Coulomb Problem: Energy Levels at the Critical Coupling Constant Analytically
Wolfgang Lucha, Franz F. Schöberl
The Hamiltonian of the spinless relativistic Coulomb problem combines the standard Coulomb interaction potential with the square-root operator of relativistic kinematics. This Hami…
New Signatures for a Light Stop at LEP2 in SUSY Models with Spontaneously Broken R-Parity
A. Bartl, W. Porod, M. A. Garcia-Jareno +3
In a class of supersymmetric models with R-parity breaking the lightest stop can have new decay modes into third generation fermions, . We show that…
