On Observing Top Quark Production at the Tevatron [PDF]
Phys.Rev.D47:967-972,1993, 1992 A technique for separating top quark production from Standard Model background events is introduced. It is applicable to the channel in which one top quark decays semi-leptonically and its anti-quark decays hadronically into three jets, or vice versa. The method is shown to discriminate dramatically between Monte Carlo generated events with and without

Electromagnetic Polarizabilities and Charge Radii of the Nucleons in the Diquark-model [PDF]
Phys.Lett. B343 (1995) 363-368, 1994 The diquark model is used to calculate the electromagnetic polarizabilities and charge radii of the nucleons for three different potentials. Making the scalar diquark lower in mass introduces a mixing angle $\theta $ between the $\left| 56\right\rangle $ and $\left| 70\right\rangle $ states ,which allows an improvement in value of all 6 properties ...

Fragmentation Functions For Baryons in a Quark-Diquark Model [PDF]
Phys.Rev. D56 (1997) 7381-7391, 1997 A perturbative QCD calculation of heavy flavor quark fragmentation into heavy flavor baryons is developed along the lines of corresponding heavy meson models. The non-perturbative formation of the baryon is accomplished by implementing the quark-diquark model of the baryons. Diquark color form factors are used to enable the integration over the virtual

The Turn of the Month Effect on CEE Stock Markets
International Journal of Financial Studies, 2019 The Turn of the month effect is one of the better-known calendar anomalies. If a stock market is affected by the Turn of the month effect, it records significantly higher returns during a relatively short time period around the end of the old month and ...

Technology in Cancer Research & Treatment, 2021 Background: Resistance to tyrosine kinase inhibitors (TKIs) in patients with chronic myeloid leukemia (CML) remains a problem in clinical treatment, and the mechanism has not been fully clarified. Autophagy can protect cancer cells under chemotherapeutic

Test of Analysis Method for Top-Antitop Production and Decay Events [PDF]
Proc.Roy.Soc.Lond.A455:2803-2834,1999, 1998 We have carried out Monte Carlo calculations on two sets of randomly generated QCD events due to $p\bar{p} \to t \bar{t}$ with top mass $m_t = 170$ GeV, one set leading to $e^+e^-$ or $e^{\pm}\mu^{\mp}$ or $\mu^+\mu^-$ 2jets (dilepton) and the other leading to $e^{\pm}$ or $\mu^{\pm}$ 4jets (unilepton) configurations, in order to test the likelihood ...

Was Viktor Orbán’s Unorthodox Economic Policy the Right Answer to Hungary’s Economic Misfortunes?
International Journal of Management and Economics, 2015 This paper assesses whether the unorthodox policies implemented in Hungary since 2010 were, given a four-year perspective, the right answer to Hungarian economic problems.

Agribusiness, EarlyView.Abstract The Russian invasion of Ukraine in February 2022 had profound consequences for the global economy. As both countries are major commodity exporters, the food value chain was also affected. This study investigates the impact of the invasion on stock prices, profitability and sentiments of agribusinesses along the food supply chain by using an ...
