The soft scalar mass β - function
We present an exact formula for the β-function for the soft-breaking scalar mass in an N = 1 supersymmetric gauge theory, in the form of an operator acting on the anomalous dimension. In particular we give the exact form for the correction due to the ǫ-scalar mass, and show that it has a particularly simple form in the renormalisation scheme corresponding to the exact NSVZ gauge β-function.
متن کاملThe Soft Régime and β Function of NRQCD
Progress towards a complete velocity power counting in non-relativistic effective field theories, especially NRQCD, is motivated and summarised. Talk presented at the “Euroconference QCD ’98” in Montpellier, France, 2nd – 8th July 1998 (to appear in Nucl. Phys. B(Proc. Suppl.)), and at the conference “Quark Confinement and the Hadron Spectrum III” at TJNL, Newport News, USA, 8th – 12th June 199...
متن کاملELECTROWEAK SYMMETRY BREAKING WITH NON - UNIVERSAL SCALAR SOFT TERMS AND LARGE tan β SOLUTIONS
We discuss radiative electroweak symmetry breaking with non-universal scalar masses at the GUT scale. Large tan β solutions are investigated in detail and it is shown that qualitatively new (as compared to the universal case) solutions exist, with much less correlation between soft terms. We identify two classes of non-universalities which give solutions with A each case, after imposing gauge a...
متن کاملIncretin Effects on β-Cell Function, Replication, and Mass
There is a progressive deterioration in b-cell function in patients with type 2 diabetes. At diagnosis, islet function may be reduced by up to 50% compared with healthy control subjects, and there is also likely to be a reduction in b-cell mass of up to 60%. The reduction in b-cell mass is due to accelerated apoptosis. Currently, few pharmacological therapies address this reduction in b-cell ma...
متن کاملSoft Scalar-Mass Sum Rule in Gauge-Yukawa Unified Models and Its Superstring Interpretation
It is shown that a certain sum rule for soft supersymmetry–breaking scalar masses, which has been recently found in a certain class of superstring models, is universal for gauge-Yukawa unified models. To explain this coincidence, we argue that the low-energy remnant of the target-space duality invariance in the effective supergravity of compactified superstrings can be identified with the (brok...
