Counter-intuition and Scalar Masses
نویسنده
چکیده
The Bousso-Polchinski mechanism for discretely fine-tuning the cosmological constant favors a large bare negative cosmological constant. I argue (using generalizations of results of Klebanov and Tseytlin) that a similar mechanism for fine-tuning the scalar masses to small values favors a large bare negative (i.e. tachyonic) scalar mass. I comment briefly on the related issue of the role of low energy supersymmetry in string theory.

Scalar Potential Topography can Simplify Interpretation of 2D Vector Fields
We demonstrate a new visualization technique to help researchers answer specific questions about 2D vector fields. Rather than directly display the vector field, the visualization isolates the integrable part of the field, integrates it to find a scalar potential, and displays the scalar potential as a height field. Scalar potential representation can be combined with direct field representatio...
متن کاملSpecific Scalar Mass Relations in SU(3)× SU(2)× U(1) Orbifold Model
We study flat directions and soft scalar masses using a Z3 orbifold model with SU(3)×SU(2)×U(1) gauge group and extra gauge symmetries including an anomalous U(1) symmetry. Soft scalar masses contain D-term contributions and particle mixing effects after symmetry breaking and they are parametrized by a few number of parameters. Some specific relations among scalar masses are obtained. e-mail: y...
متن کاملLarge Squark and Slepton Masses for the First - Two Generations in the Anomalous U ( 1 ) SUSY Breaking Models
Considering that the soft SUSY breaking scalar masses come from a vacuum expectation value of the D-term for an external gauge multiplet, the renormalization of the scalar masses is related to the gauge anomaly. Then, if the external gauge symmetry is anomaly-free, the scalar masses are nonrenormalized at all orders assuming that the gaugino masses are negligibly small compared with the scalar ...

The contributions into radiative correction parameters S, T, U from scalar leptoquark and scalar gluon doublets are investigated in the minimal four color symmetry model. It is shown that the existence of the relatively light scalar leptoquarks and scalar gluons (with masses of order of 1 TeV or less) is consistent with the current experimental data on S, T, U and the more light particles (with...
متن کاملScreening properties of quark–anti-quark correlators in deconfined medium
We present results for the inverse screening lengths (i.e. the screening masses) of quark–antiquark systems belonging to different spin-parity channels. The results are obtained from lattice QCD simulations of 2 + 1 flavors of dynamical quarks with masses that correspond to realistic pion and almost physical kaon masses at zero temperature. For the light quarks our study shows that the screenin...
