String Landscape and Supernovae Ia
L. Clavelli
We present a model for the triggering of Supernovae Ia (SN Ia) by a phase transition to exact supersymmetry (susy) in the core of a white dwarf star. The model, which accomodates t…
Nuclear Physics in a Susy Universe
L. Clavelli, I. Perevalova
We refine a previous zeroth order analysis of the nuclear properties of a supersymmetric (susy) universe with standard model particle content plus degenerate susy partners. No assu…
Probing Metastability at the LHC
L. Clavelli
Current attempts to understand supersymmetry (susy) breaking are focused on the idea that we are not in the ground state of the universe but, instead, in a metastable state that wi…
Metastable Aspects of Singlet Extended Higgs Models
L. Clavelli
It has long been known that the broken supersymmetric (susy) phase of the singlet extended susy higgs model (SESHM) is at best metastable and the ground states of the model have va…
Extended Higgs Models and a Transition to Exact Susy
L. Clavelli
String landscape ideas and the observation of a positive vacuum energy in the current universe suggest that there could be a future transition to an exactly supersymmetric world. A…
Landscape Implications of Extended Higgs Models
L. Clavelli
From several points of view it is strongly suggested that the current universe is unstable and will ultimately decay to one that is exactly supersymmetric (susy). The possibility t…
Phase Transition to Exact Susy
L. Clavelli
The anthropic principle is based on the observation that, within narrow bounds, the laws of physics are such as to have allowed the evolution of life. The string theoretic approach…
Ionic Binding in a Susy Background
L. Clavelli, T. Lovorn
From string theory and the observation of a positive vacuum energy in our universe it seems inevitable that there will eventually be a phase transition to an exactly supersymmetric…
Problems in a weakless universe
L. Clavelli, R. E. White
The fact that life has evolved in our universe constrains the laws of physics. The anthropic principle proposes that these constraints are sometimes very tight and can be used to e…
Neighboring Valley in the String Landscape
L. Clavelli
The observation in the universe of a small but positive vacuum energy strongly suggests, in the string landscape picture, that there will ultimately be a phase transition to an exa…
Gravitational collapse of a susy star
L. Clavelli
The evidence for a positive vacuum energy in our universe suggests that we might be living in a false vacuum destined to ultimately decay to a true vacuum free of dark energy. At p…
Growth of a susy bubble: inhomogeneity effects
L. Clavelli
In a dense star, the Pauli exclusion principle functions as an enormous energy storage mechanism. Supersymmetry could provide a way to recapture this energy. If there is a transiti…
A Susy Phase Transition as Central Engine
L. Clavelli
For several decades the energy source powering supernovae and gamma ray bursts has been a troubling mystery. Many articles on these phenomena have been content to model the consequ…
A supersymmetric origin of gamma ray bursts
L. Clavelli
Bright bursts of gamma rays from outer space have been puzzling Astronomers for more than thirty years and there is still no conceptually complete model for the phenomenon within t…
Electron to selectron pair conversion in a SUSY bubble
L. Clavelli, I. Perevalova
In the standard model, energy release in dense stars is severely restricted by the Pauli exclusion principle. However, if, in regions of space of high fermion degeneracy, there is…
A supersymmetric model of gamma ray bursts
L. Clavelli, G. Karatheodoris
We propose a model for gamma ray bursts in which a star subject to a high level of fermion degeneracy undergoes a phase transition to a supersymmetric state. The burst is initiated…
R Parity Violating Decays of the Gluino
L. Clavelli, H. Stremnitzer
Assuming the lightest supersymmetric particle is the gluino, we treat the decays gluino->quark-antiquark-neutrino and gluino->gluon-neutrino. Such couplings can be induced by the R…
Beyond the Zero-Binding Approximation in Quarkonium
L. Clavelli, P. H. Cox, T. Gajdosik
The hadronic decays of quarkonium and the B meson inclusive decay into J/Psi + X, if treated in the zero-binding approximation, suggest a value of the strong coupling constant much…
Quarkonium Polarization in Lepton Annihilation
L. Clavelli, P. Coulter, T. Gajdosik
We investigate the polarization properties of vector quarkonia in lepton anti-lepton annihilation with special attention to effects due to intermediate Z bosons.
Parity and Time Reversal in J/Psi Decay
L. Clavelli, T. Gajdosik, I. Perevalova
With the prospect of large numbers of decay events becoming available in the near future, it is interesting to search for symmetry violating effects as probes of new physics…
Upsilon Decay to a Pair of Bottom Squarks
Edmond L. Berger, L. Clavelli
We calculate the rate for decay into a pair of bottom squarks as a function of the masses of the bottom squark and the gluino. Data from decays of the states could provide…
Gaugino Mass Dependence of Electron and Neutron Electric Dipole Moments
L. Clavelli, T. Gajdosik, W. Majerotto
Unless squarks and sleptons are in the multi-TeV region or above, CP violating induced electric dipole moments of elementary particles can pose significant puzzles for supersymmetr…
Report of the Beyond the MSSM Subgroup for the Tevatron Run II SUSY/Higgs Workshop
S. Ambrosanio, H. Baer, A. Brignole +30
There are many low-energy models of supersymmetry breaking parameters which are motivated by theoretical and experimental considerations. Here, we discuss some of the lesser-known…
New Possibilities for a Light Gluino
L. Clavelli
Despite many positive indirect indications of light gluinos direct searches for the expected signatures of gluino containing hadrons have so far turned up negative severely restric…
