Production of rare particles within rapidity gaps has been proposed as a background-free signal for the detection of new physics at hadron colliders. No complete formalism accounts for such processes yet. We study a simple lowestorder QCD model for their description. Concentrating on Higgs production, we show that the calculation of the cross section pp → ppH can be embedded into existing model...

We apply the phenomenological Reggeon field theory framework to investigate rapidity gap survival (RGS) probability for diffractive dijet production in proton-proton collisions. In particular, we study in some detail rapidity gap suppression due to elastic rescatterings of intermediate partons in the underlying parton cascades, described by enhanced (Pomeron-Pomeron interaction) diagrams. We de...

Photon splitting is a QED process that can potentially suppress pair production in the inner magnetosphere of a pulsar with a super-strong magnetic field, and hence, may quench radio emission from these objects. While it is unknown how many splitting modes really operate in supercritical fields, we derive gap parameters of a high magnetic field pulsar for both the vacuum-type gap and the space-...

corporate social responsibility is a concept whereby companies integrate social and environmental concerns in their business activities and interactions  with their stakeholders on a voluntary basis. in this global context, voluntary social and environmental practices of business which go beyond companies’ existing legal obligations play a major role in filling the governance gap in an innovati...

Background: Investment in science is vital for the development and well-being of societies. This study aims to assess the scientific productivity of countries by quantifying their publication of systematic reviews taking the gross national income per capita (GNIPC) into account. Methods: Medline and ISI Web of Science were searched for systematic reviews published between 1st January 2006 an...

Low soil fertility and high weed infestation are the main culprits for the declining maize production inWestern Kenya. Technology packages to address these constraints exist, but their effectiveness is likely to be influenced by variability in soil types and farm management practices in the region. Trials were conducted during the 2008/2009 cropping seasons to investigate the nutrient use e...
