Signatures of Resonant Super-Partner Production with Charged-Current Decays

Hadron collider signatures of new physics are investigated in which a primary resonance is produced that decays to a secondary resonance by emitting a W-boson, with the secondary resonance decaying to two jets. This topology can arise in supersymmetric theories with R-parity violation where the lightest supersymmetric particles are either a pair of squarks, or a slepton - sneutrino pair. The resulting signal can have a cross section consistent with the Wjj observation reported by the CDF collaboration, while remaining consistent with earlier constraints. Other observables that can be used to confirm this scenario include a significant charge asymmetry in the same channel at the LHC. With strongly interacting resonances such as squarks, pair production topologies additionally give rise to 4 jet and WW + 4 jet signatures, each with two equal-mass dijet resonances within the 4 jets.Comment: Note added for recent developments concerning the Wjj final state.

1995 PRICING PERFORMANCE OF MARKET ADVISORY SERVICES FOR CORN AND SOYBEANS

The purpose of this research report is to present an evaluation of advisory service pricing performance in 1995 for corn and soybeans. Specifically, the average price received by a subscriber to an advisory service is calculated for corn and soybean crops harvested in 1995. The average net advisory price across all 25 corn programs is $3.04 per bushel. The range of net advisory prices for corn is quite large, with a minimum of$2.34 per bushel and a maximum of $3.81 per bushel. The average net advisory price across all 25 soybean programs is$6.61 per bushel. As with corn, the range of net advisory prices for soybeans is substantial, with a minimum of $5.75 per bushel and a maximum of$7.92 per bushel.Agricultural Market Advisory Service (AgMAS) Project, D4, D7, D8, G1, G2, H4, H8, Q1, Z1, Marketing,

1997 PRICING PERFORMANCE OF MARKET ADVISORY SERVICES FOR CORN AND SOYBEANS

The purpose of this research report is to present an evaluation of advisory service pricing performance in 1997 for corn and soybeans. Specifically, the average price received by a subscriber to an advisory service is calculated for corn and soybean crops harvested in 1997. The average net advisory price across all 23 corn programs is $2.32 per bushel. The net advisory prices for corn range from a minimum of$2.00 per bushel to a maximum of $2.74 per bushel. The average net advisory price across all 21 soybean programs is$6.40 per bushel. The net advisory prices for soybeans range from a minimum of $6.08 per bushel to a maximum of$6.99 per bushel.evaluation of advisory services, pricing performance, soybeans, C8, D4, D8, L1, M3, Q0, Z0, Marketing,

DEVELOPMENT OF A MARKET BENCHMARK PRICE FOR AGMAS PERFORMANCE EVALUATIONS

The purpose of this research report is to identify the appropriate market benchmark price to use to evaluate the pricing performance of market advisory services that are included in the annual AgMAS pricing performance evaluations. Five desirable properties of market benchmark prices are identified. Three potential specifications of the market benchmark price are considered: the average price received by Illinois farmers, the harvest cash price, and the average cash price over a two-year crop marketing window. The average cash price meets all of the desired properties, except that it would not be easily implementable by producers. It can be shown, though, that the price realized via a more manageable strategy of "spreading" sales during the marketing window very closely approximates the average cash price. Therefore, it is determined that the average cash price meets all five selection criteria, and is the most appropriate market benchmark to be used in evaluating the pricing performance of market advisory services.advisory services, evaluating the pricing performance, market benchmark price, C8, C0, D4, D8, L1, M3, Q0, Z0, Marketing,

Application of CFD to sonic boom near and mid flow-field prediction

A 3-D parabolized Navier-Stokes (PNS) code was used to calculate the supersonic overpressures from three different geometries at near- and mid-flow fields. Wind tunnel data is used for code validation. Comparison of the computed results with different grid refinements is shown. It is observed that a large number of grid points is needed to resolve the tail shock/expansion fan interaction. Therefore, an adaptive grid approach is employed to calculate the flow field. The agreement between the numerical results and the wind tunnel data confirms that computational fluid dynamics can be applied to the problem of sonic boom prediction

1996 PRICING PERFORMANCE OF MARKET ADVISORY SERVICES FOR CORN AND SOYBEANS

The purpose of this research report is to present an evaluation of advisory service pricing performance in 1996 for corn and soybeans. Specifically, the average price received by a subscriber to an advisory service is calculated for corn and soybean crops harvested in 1996. The average net advisory price across all 26 corn programs is $2.63 per bushel. The range of net advisory prices for corn is quite large, with a minimum of$2.08 per bushel and a maximum of $3.12 per bushel. The average net advisory price across all 24 soybean programs is$7.27 per bushel. As with corn, the range of net advisory prices for soybeans is substantial, with a minimum of $6.80 per bushel and a maximum of$7.80 per bushel.Agricultural Market Advisory Services, G1, D8, D7, D4, G2, H4, H8, Q1, Z1, Marketing,

DO AGRICULTURAL MARKET ADVISORY SERVICES BEAT THE MARKET? EVIDENCE FROM THE CORN AND SOYBEAN MARKETS OVER 1995-1997

The purpose of this paper is to address two basic performance questions for market advisory services: 1) Do market advisory services, on average, outperform an appropriate market benchmark? and 2) Do market advisory services exhibit persistence in their performance from year-to-year? Data on corn and soybean net price received for advisory services, as reported by the AgMAS Project, are available for the 1995, 1996 and 1997 marketing years. Performance test results suggest that, on average, market advisory services exhibit a small ability to "beat the market" for the 1995 through 1997 corn and soybean crops. This conclusion is somewhat sensitive to the type of performance test and market benchmark considered. The predictability results provide little evidence that future advisory service pricing performance can be predicted from past performance. When services are grouped by performance quantile, some evidence of predictability is found for the poorest performing services, but not for top performing services.Marketing,

THE PRIVATE SECTOR APPROACH TO GRAIN MARKETING: THE CASE OF AGRICULTURAL MARKET ADVISORY SERVICES

The purpose of this paper is to investigate the pricing performance and behavior of market advisory services in corn and soybeans. Data on corn and soybean net price received for advisory services, as reported by the AgMAS Project, are available for the 1995, 1996 and 1997 marketing years. Performance test results suggest that, on average, market advisory services exhibit a small ability to "beat the market". This conclusion is somewhat sensitive to the type of performance test and market benchmark considered. The predictability results provide little evidence that future advisory service pricing performance can be predicted from past performance. Marketing profiles identify three marketing "styles": i) "scale-up" sales, ii) selective hedging and iii) "speculative" hedging. Advisory services tend to follow the same approach across crop years.Agribusiness,

DO AGRICULTURAL MARKET ADVISORY SERVICES BEAT THE MARKET? EVIDENCE FROM THE CORN AND SOYBEAN MARKETS OVER 1995-1998

The purpose of this paper is to address two basic performance questions for market advisory services: 1) Do market advisory services, on average, outperform an appropriate market benchmark? and 2) Do market advisory services exhibit persistence in their performance from year-to-year? Data on corn and soybean net price received for advisory services, as reported by the AgMAS Project, are available for the 1995, 1996, 1997 and 1998 crop years. Performance test results suggest that, on average, market advisory services exhibit a small ability to "beat the market" for the 1995 through 1998 corn and soybean crops. It is debatable whether the performance of advisory services also is economically significant. The predictability results provide little evidence that future advisory service pricing performance can be predicted from past performance.Marketing,
