Instance Methods

[hide private]

default_setup(self)
Default values for all properties

source code

filter(self, name, value)
Filter for valid process property values.

source code

get_sorted_keys(self)
Return process property names as a nicely sorted list.

source code

get_minimum_WEIGHTED(self)
Retrieve the minimum starting guess for WEIGHTED order, to use in find_optimal_process_orders in MultiProcess diagram generation (as well as particles and hierarchy).

source code

nice_string(self, indent=0)
Returns a nicely formated string about current process content

source code

__eq__(self, other)
Overloading the equality operator, so that only comparison of process id and legs is being done, using compare_for_sort.

default_setup(self)

source code

Default values for all properties

Overrides: PhysicsObject.default_setup

filter(self, name, value)

source code

Filter for valid process property values.

Overrides: PhysicsObject.filter

get_sorted_keys(self)

source code

Return process property names as a nicely sorted list.

Overrides: PhysicsObject.get_sorted_keys

get_minimum_WEIGHTED(self)

source code

Retrieve the minimum starting guess for WEIGHTED order, to use in find_optimal_process_orders in MultiProcess diagram generation (as well as particles and hierarchy). The algorithm:

1) Pick out the legs in the multiprocess according to the highest hierarchy represented (so don't mix particles from different hierarchy classes in the same multiparticles!)

2) Find the starting maximum WEIGHTED order as the sum of the highest n-2 weighted orders

3) Pick out required s-channel particle hierarchies, and use the highest of the maximum WEIGHTED order from the legs and the minimum WEIGHTED order extracted from 2*s-channel hierarchys plus the n-2-2*(number of s-channels) lowest leg weighted orders.

nice_string(self, indent=0)

source code

Returns a nicely formated string about current process content

Overrides: Process.nice_string

eq(self, other)
(Equality operator)

source code

Overloading the equality operator, so that only comparison of process id and legs is being done, using compare_for_sort.
