From novel mathematics to efficient algorithms. Do we have proper SD foundation to build future?
F. V. Tkachov
Computer implementation of sophisticated algorithms for physics applications is greatly facilitated by the new generation of component-oriented SD technologies pioneered by Wirth's…
A verification of the Optimal Jet Finder
F. V. Tkachov
The fortran-77 code [hep-ph/9912415] of the jet algorithm based on the optimal jet definition [hep-ph/9901444] has been successfully verified (up to a few interface bugs) using an…
On the large-s behavior of total cross sections in perturbative QCD
F. V. Tkachov
Reported is a factorization theorem for large-s behavior of total cross sections obtained in a straightforward fashion from ordinary perturbation theory. The theorem extends the st…
On the structure of systematic perturbation theory with unstable fields
Fyodor V. Tkachov
Discussed is the structure of non-trivial counterterms that occur in the systematic gauge-invariant perturbation theory with unstable fields introduced in [hep-ph/9802307].
Approaching the parameter estimation quality of maximum likelihood via generalized moments
Fyodor V. Tkachov
A simple criterion is presented for a practical construction of generalized moments that allow one to approach the theoretical Rao-Cramer limit for parameter estimation while avoid…
Perturbation theory with unstable fundamental fields
Fyodor V. Tkachov
The difficulties of perturbation theory associated with unstable fundamental fields (such as the lack of exact gauge invariance in each order) are cured if one constructs perturbat…
