Large mass splittings between charged and neutral Higgs bosons in the MSSM

We show that large ($> 100$ GeV) mass splittings between the charged Higgs boson ($H^\pm$) and the neutral Higgs bosons ($H^0$ and $A^0$) are possible in the Minimal Supersymmetric Standard Model (MSSM). Such splittings occur when the $\mu$ parameter is considerably larger than the common SUSY scale, $M_{SUSY}$, and have significant consequences for MSSM Higgs searches at future colliders.Comment: 11 pages, LaTex, 5 figures, version to appear in Phys.

Report of the Higgs Working Group of the Tevatron Run 2 SUSY/Higgs Workshop

This report presents the theoretical analysis relevant for Higgs physics at the upgraded Tevatron collider and documents the Higgs Working Group simulations to estimate the discovery reach in Run 2 for the Standard Model and MSSM Higgs bosons. Based on a simple detector simulation, we have determined the integrated luminosity necessary to discover the SM Higgs in the mass range 100-190 GeV. The first phase of the Run 2 Higgs search, with a total integrated luminosity of 2 fb-1 per detector, will provide a 95% CL exclusion sensitivity comparable to that expected at the end of the LEP2 run. With 10 fb-1 per detector, this exclusion will extend up to Higgs masses of 180 GeV, and a tantalizing 3 sigma effect will be visible if the Higgs mass lies below 125 GeV. With 25 fb-1 of integrated luminosity per detector, evidence for SM Higgs production at the 3 sigma level is possible for Higgs masses up to 180 GeV. However, the discovery reach is much less impressive for achieving a 5 sigma Higgs boson signal. Even with 30 fb-1 per detector, only Higgs bosons with masses up to about 130 GeV can be detected with 5 sigma significance. These results can also be re-interpreted in the MSSM framework and yield the required luminosities to discover at least one Higgs boson of the MSSM Higgs sector. With 5-10 fb-1 of data per detector, it will be possible to exclude at 95% CL nearly the entire MSSM Higgs parameter space, whereas 20-30 fb-1 is required to obtain a 5 sigma Higgs discovery over a significant portion of the parameter space. Moreover, in one interesting region of the MSSM parameter space (at large tan(beta)), the associated production of a Higgs boson and a b b-bar pair is significantly enhanced and provides potential for discovering a non-SM-like Higgs boson in Run 2.Comment: 185 pages, 124 figures, 55 table

Victory vegetable gardens

The farm garden may easily occupy 1/2 acre and supply enough vegetables for a medium-sized family the year around. The garden on the city lot necessarily will have to be smaller, but by intensive methods of cropping may be made to produce enough fresh vegetables during the growing season for a small-sized family. Farm gardens are often too small for the needs of the family, because the labor required by a larger garden is thought to interfere with farm duties. Using field methods of tillage, the size of the farm garden can be increased with no increase in labor. Many farm gardens should be relocated because continuous cropping without adequate rotation has reduced yields and quality of the vegetables. Soils for vegetable crops should be high in organic matter. The easiest way to secure this is through the application of animal manure or the plowing under of a green manure crop, preferably a legume. A good plan for the farm vegetable garden would be to plant an area in soybeans or other legumes equal to that planted to vegetables. The next year plant the vegetables on that portion of the garden in which the green manure was grown. Select a level site or one with a gentle slope, avoiding steep slopes because small seeds and seedlings easily wash out with heavy rains. North and east exposures are preferable since they do not dry out as readily and are cooler. Protection from winds is always desirable, but of course vegetables will not grow well close to tree rows or in the shade of buildings
