Evaluating double and triple (?) boxes
نویسنده
چکیده
A brief review of recent results on analytical evaluation of double-box Feynman integrals is presented. First steps towards evaluation of massless on-shell triple-box Feynman integrals within dimensional regularization are described. The leading power asymptotic behaviour of the dimensionally regularized massless on-shell master planar triple-box diagram in the Regge limit t/s → 0 is evaluated. The evaluation of the unexpanded master planar triple box is outlined and explicit results for coefficients at 1/ǫ , j=2,. . . ,6, are presented.

The coefficients of differentiated expansions of double and triple Jacobi polynomials
Formulae expressing explicitly the coefficients of an expansion of double Jacobi polynomials which has been partially differentiated an arbitrary number of times with respect to its variables in terms of the coefficients of the original expansion are stated and proved. Extension to expansion of triple Jacobi polynomials is given. The results for the special cases of double and triple ultraspher...
متن کاملComparison of triple and double phototherapy in neonatal hyperbilirubinemia
Introduction: Icterus is the most common medical problem in neonates. Phototherapy is standard treatment of neonatal hyperbilirubinemia. This study aims to compare efficacy and length of hospitalization of double and triple phototherapy in term newborns with indirect hyperbilirubinemia. Methods: In a randomized clinical trial 40 healthy term newborns (gestational age>37 weeks) with weight≥250...

In order to evaluate the benefits of maize, pinto bean and naked pumpkin triple cropping, an experiment was carried out as a randomized complete block design with three replications at Faculty of Agricultural Science, University of Guilan, Rasht, Iran in 2012. The treatments consisted of maize, pinto bean and naked pumpkin sole cropping (100, 75 and 50% of conventional densities), maize – pinto...
متن کاملCalculation of the triple and double cross sections in the proton-hydrogen impact at the ionization channel by removing singularity in the scattering amplitudes
In the present work, the triple and double cross sections of atomic hydrogen ionization in collision with the proton are calculated. The potential of the interaction is considered as a Coulombic; also, the first and second order Born approximations have been used. The singularity of the Green operator in the second order approximation has been removed for the analytical solution of the scatt...
متن کاملEffects of Triple Injection Strategies on Performance and Pollutant Emissions of a DI Diesel Engine Using CFD Simulation
One of the main controlling parameters in diesel engine combustion is the fuel – air mixing process that has direct effects on engine performance and pollutant emissions, reviewing over previous literature showed that split injection strategies could satisfy this purpose very well. For the first time and in this paper, pilot and double injection strategies were combined and formed new triple in...
