Evaluating double and triple (?) boxes
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....
متن کاملAnalytical Evaluation of Dimensionally Regularized Massive On-Shell Double Boxes
The method of Mellin–Barnes representation is used to calculate dimensionally regularized massive on-shell double box Feynman diagrams contributing to Bhabha scattering at two loops.
متن کاملǫ-Expansion for non-planar double-boxes
We present calculations for non-planar double-box with four massless/massive external/internal legs/propagators. The results are expressed for arbitrary exponents of propagators and dimension in terms of Lauricella’s hypergeometric functions of three variables and hypergeometric-like multiple series.
متن کاملRosettes for elongation
A blob becomes a body by becoming thinner and longer— a process that involves cell shuffl ing called intercalation. Flies do it by making and resolving rosettes of cells, Up to 11 cells join these pinwheels, which squeeze together cells that were arrayed in the dorsal–ventral axis, before letting them relax back into a line running from anterior to posterior. The rosettes are striking, but it h...
متن کاملPolyoxotungstates in Molecular Boxes of Purine Bases
Three new compounds, (GuaH)4[W10O32](H2O)4 (1), (ThbH)3(H3O)[(W10O32](H2O)7.5 (2) and (ThbH)2[W6O19](H2O)2 (3) (GuaH = guaninium, thbH = theobrominium) were synthesized in acidified acetonitrile solutions. The polyoxotungstates in all of these compounds are surrounded by an organic matrix consisting of protonated purine bases and water molecules. The distinctive structural arrangement of the ar...
