W/Z+jets measurements at DZero [article]

Darren D. Price
2011 arXiv   pre-print
We present a summary of recent measurements of vector boson production in association with jets in pp̅ collisions at √(s)=1.96 TeV with the DØ detector. Results of measurements of the inclusive n-jet cross-sections, σ_n/σ_n-1 ratios of W+(n)jet production for n=0-4 and the normalized n^th jet p_T differential cross-section distributions, and measurement of the production cross-section (times branching fraction) ratio of Z+b-jet to Z+jet production are reported. Measurement of the normalized

Latest jet results from the Tevatron [article]

Darren D. Price
2010 arXiv   pre-print
A brief overview of the latest status of jet physics studies at the Tevatron in proton-antiproton collisions at √(s)=1.96 TeV is presented. In particular, measurements of the inclusive jet production cross-section, dijet production and searches for new physics, the ratio of the 3-jet to 2-jet production cross-sections, and the three-jet mass are discussed.

Harvest contract price volatility for cotton

Darren Hudson, Keith Coble
1999 Journal of futures markets  
That is, as futures prices increased, price volatility also tended to increase. This is not a surprising in that higher prices have "more room to move" than lower prices, in general.  ...  The average monthly futures price is directly and significantly related to price volatility. This suggests that as the price level increases, price volatility also tends to increase.  ...

On perceptions of financial volatility in price sequences

Darren Duxbury, Barbara Summers
2017 European Journal of Finance  
Also of interest is the influence of price sequence regularity on perceived volatility.  ...  Furthermore, we report evidence to support the view that the extent to which prices appear irregular is a separate aspect of volatility, distinct from the extent to which prices deviate from central tendency  ...  Participants either observe graphs of price sequences alone or graphs of both price sequences and price changes.  ...

Search for Standard Model Higgs in WH->lvbb at the Tevatron [article]

Darren D. Price
2009 arXiv   pre-print
We present a search for the Standard Model Higgs boson produced in association with a W boson in pp̅ collisions at a center-of-mass energy of √(s) = 1.96 TeV. The search is performed in the WH→ℓν bb̅ channel using 2.7 fb^-1 of data collected by both the CDF detector and by the DØ detector, at the Fermilab Tevatron. The searches employ artificial neural network, matrix element and boosted decision tree techniques to improve the separation between signal and background. Additional techniques used
more » ... to improve the Higgs sensitivity include the use of optimized b-quark jet energy corrections and improved algorithms for identifying b-quarks. In the absence of an observed excess in data, upper limits are set by both experiments on the Higgs production rate times branching ratio for a range of possible Higgs masses between 100 and 150 GeV.

Exploring the price of motor vehicle collisions – A compensation cost approach

Darren Shannon, Luis Rizzi, Finbarr Murphy, Martin Mullins
2020 Transportation Research Interdisciplinary Perspectives  
Motor Vehicle Collisions (MVCs) accounted for an economic cost of $242 billion in the United States in 2010. A significant portion (42%) was associated with factors considered for compensation estimatesmedical costs, lost earnings and reduced household productivity. This study proposes a methodology that accounts for these costs by using expected compensation costs (ECCs). Our approach differs from prior studies as we consider all injuries suffered by an individual in the MVC, rather than only
more » ... he 'most severe' injury. We estimate ECCs for each injured occupant by linking the injuries suffered with guidelines on injury compensations, allowing for ECCs to be linked directly with collision factors. To demonstrate the ECC system, we conduct a cross-sectional mediation analysis to study the relationships between collisions and compensation. delta-V (the change in a vehicle's speed pre-and post-crash) remains a primary factor in the severity of MVCs and so it serves as a focal point in our study. We find that some collision factors influence compensation estimates because of the effects of delta-V, while others influence ECCs regardless of delta-V. The ECC system we introduce can mitigate litigation risk and highlight future approaches to road safety, as it bridges the gap between crash characteristics, injuries suffered, and economic damage. Our results support policy recommendations that promote seatbelt use and warn against alcohol-impaired driving, and support the proliferation of safety-enabled vehicles whose technology can mitigate the economic damage associated with detrimental crash types.

Is Systematic Downside Beta Risk Really Priced? Evidence in Emerging Market Data

Don (Tissa) U. A. Galagedera, Robert Darren Brooks
2005 Social Science Research Network  
This study addresses this issue by including downside co-skewness risk in addition to the downside beta risk in the pricing model.  ...  In a sample of 27 emerging markets two-stage rolling regression analysis fail to support pricing models with downside risk measures.  ...  Hence we conduct further tests to determine whether or not downside beta and downside gamma is priced when the CAPM beta is in the pricing model.  ...

The Relationship between Oil, Exchange Rates, and Commodity Prices

Ardian Harri, Lanier Nalley, Darren Hudson
2009 Journal of Agricultural and Applied Economics  
In this paper, we examine the price relationship through time of the primary agricultural commodities, exchange rates, and oil prices.  ...  In general, we find that commodity prices are linked to oil for corn, cotton, and soybeans, but not for wheat, and that exchange rates do play a role in the linkage of prices over time.  ...  Finally, oil affects commodity production (and, thus, price) through input prices.  ...

Quarkonium production at ATLAS

Darren D. Price
2012 EPJ Web of Conferences  
The production of quarkonium is an important testing ground for QCD calculations. The J/ψ and Υ production cross-sections are measured in proton-proton collisions at a centre-of-mass energy of 7 TeV with the ATLAS detector at the LHC. Differential cross-sections are presented as a function of transverse momentum and rapidity. The fraction of J/ψ produced in B-hadron decays is also measured and the differential cross-sections of prompt and non-prompt J/ψ production determined separately.
