We compute total cross sections for various slepton pair production reactions l̃Lν̃L, l̃L ̄̃ lL, l̃R ̄̃ lR and ν̃L ̄̃ νL in next-to-leading order QCD. For pp̄ collisions at √ S = 2 TeV, we find leading order cross sections to be enhanced by typically 35% to 40%. For pp collisions at √ S = 14 TeV, the enhancement ranges from 25% to 35% depending on the mass of the sleptons. We comment upon the phenomenolog...

the present research proposes and optimizes the performance of a novel solar-driven combined cooling, heating, and power (cchp) kalina system for two seasons—winter and summer—based on exergy, exergo-economic, and exergo-environmental concepts applying a non-dominated sort genetic algorithm-ii (nsga-ii) technique. three criteria, i.e. daily exergy efficiency, total product cost rate, and total ...

embryo transfer (et) in holstein dairy cattle became an important commercial enterprise after the introduction of non-surgical recovery technique. embryo transfer could increase the reproductive rate of genetically superior cows. the objectives of the present study were to evaluate the use of et in iranian holstein dairy cattle to increase selection intensity on the dam side, economically; esti...

in recent years, sexed semen has been commercially available. due to its lower fertility and higher price compared to conventional semen, economic evaluation should be undertaken before recommending the technology to dairy producers in each country. the objectives of the present study were to evaluate the advantages and disadvantages of the sexed semen usage at farm level in economic conditions...

In the current LHC run, an accurate understanding of Standard Model processes is extremely important. Processes including electroweak gauge bosons serve as standard candles for SM measurements, and equally constitute important backgrounds for Beyond-the-Standard Model (BSM) searches. We present here the next-to-leading order (NLO) QCD virtual contributions to W+W−+jet in an analytic format obta...

We present updated predictions for the total cross section of top-quark pair production at Tevatron and LHC. For the LHC we also provide results at √ s = 10 TeV, in view of the anticipated run in 2008 and quote numbers for the production of new heavy-quark pairs with mass in the range 0.5 – 2 TeV. Our two-loop results incorporate all logarithmically enhanced terms near threshold including Coulo...
