Higgs boson production in e+e- --> b
No full textThe production of the Standard Model Higgs boson in the four-fermion reaction e^+ e^- \to \mu^+ \mu^- b \bar b is studied. The complete tree-level matrix element, including signal and backgrounds in the standard electroweak theory, is computed and initial state radiation is taken into account in the leading-log approximation. A Monte Carlo event generator has been built and numerical results for some distributions of experimental interest for the search of the Higgs particle at future electron-positron colliders are shown, compared with those existing in the literature and commented.The production of the Standard Model Higgs boson in the four-fermion reaction is studied.

WWGENPV: a Monte Carlo event generator for four-fermion production in e+e- --> WW --> 4f
No full textThe Monte Carlo program {\tt WWGENPV}, designed for computing distributions and generating events for the four-fermion process e^+ e^- \to W^+ W^- \to 4f, is described. It is based on the calculation of the exact tree-level matrix element of the four-fermion reaction and includes initial-state radiation in the leading-log approximation within the structure function approach. The program can be used in a two-fold way: as a Monte Carlo integrator for weighted events, providing predictions for the total cross section, the W invariant-mass distribution, the radiative energy and invariant-mass loss; as a true event generator of unweighted events, useful for simulation purposes.The Monte Carlo program {\tt WWGENPV}, designed for computing distributions and generating events for the four-fermion process , is described.

Efficient Option Pricing with Path Integral
No full textAn efficient computational algorithm to price
financial derivatives is presented. It is based on a path integral
formulation of the pricing problem. It is shown how the path integral
approach can be worked out in order to obtain fast and accurate
predictions for the value of a large class of
options, including those with path-dependent and early exercise
features. As examples, the application of the method to European and
American options in the Black-Scholes model is illustrated.
The results of the algorithm are compared with those obtained with the standard
procedures known in the literature and found to be in good agreement
