Supersymmetry with Small mu: Connections between Naturalness, DarkMatter, and (Possibly) Flavor (open access)

Supersymmetry with Small mu: Connections between Naturalness, DarkMatter, and (Possibly) Flavor

Weak scale supersymmetric theories often suffer from several naturalness problems: the problems of reproducing the correct scale for electroweak symmetry breaking, the correct abundance for dark matter, and small rates for flavor violating processes. We argue that the first two problems point to particular regions of parameter space in models with weak scale supersymmetry: those with a small {mu} term. This has an interesting implication on direct dark matter detection experiments. We find that, if the signs of the three gaugino mass parameters are all equal, we can obtain a solid lower bound on the spin-independent neutralino-nucleon cross section, {sigma}{sub SI}. In the case that the gaugino masses satisfy the unified mass relations, we obtain {sigma}{sub SI} {approx}> 4 x 10{sup -46} cm{sup 2} (1 x 10{sup -46} cm{sup 2}) for fine-tuning in electroweak symmetry breaking no worse than 10% (5%). We also discuss a possibility that the three problems listed above are all connected to the hierarchy of fermion masses. This occurs if supersymmetry breaking and electroweak symmetry breaking (the Higgs fields) are coupled to matter fields with similar hierarchical structures. The discovery of {mu} {yields} e transition processes in near future experiments is predicted in such a framework.

2006 Multiphoton Processes Gordon Conference - June 11-16 (open access)

2006 Multiphoton Processes Gordon Conference - June 11-16

The first Gordon Research Conference on Multiphoton Processes, was held in 1982. The meeting continues to evolve as it embraces both the rapid technological and intellectual growth in the field as well as the multi-disciplinary expertise of the participants. Current areas of interest include: (1) Ionization/Dissociation of Atoms and Molecules in Intense Laser Fields; (2) Frequency Domain Multi-Photon and Multiple-Resonance Spectroscopies of Molecules; (3) Time-Resolved Photoelectron Spectroscopy; (4) Ultrafast Pump-Probe Spectroscopy; (5) Coherent Strong-Field Manipulation of Atoms and Molecules; (6) High-Harmonic Generation; (7) Attosecond Pulse Generation and Measurement; and (8) Super-Intense Laser-Matter Interactions. In developing the program, the conference organizers will strive to blur traditional disciplinary boundaries, involving chemists, physicists, and optical engineers, representing both experiment and theory, as presenters and discussion leaders. The broad range of expertise and different perspectives of attendees should provide a stimulating and unique environment for solving problems and developing new ideas in this rapidly evolving field.
