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

set(self, name, value)
Special set for forbidden particles - set to abs value.

source code

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

source code

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

source code

input_string(self)
Returns a process string corresponding to the input string in the command line interface.

source code

base_string(self)
Returns a string containing only the basic process (w/o decays).

source code

shell_string(self, schannel=True, forbid=True, main=True)
Returns process as string with '~' -> 'x', '>' -> '_', '+' -> 'p' and '-' -> 'm', including process number, intermediate s-channels and forbidden particles

source code

shell_string_v4(self)
Returns process as v4-compliant string with '~' -> 'x' and '>' -> '_'

source code

get_ninitial(self)
Gives number of initial state particles

source code

get_initial_ids(self)
Gives the pdg codes for initial state particles

source code

get_initial_pdg(self, number)
Return the pdg codes for initial state particles for beam number

source code

get_final_legs(self)
Gives the final state legs

source code

get_final_ids(self)
Gives the pdg codes for final state particles

source code

get_legs_with_decays(self)
Return process with all decay chains substituted in.

source code

list_for_sort(self)
Output a list that can be compared to other processes as: [id, sorted(initial leg ids), sorted(final leg ids), sorted(decay list_for_sorts)]

source code

compare_for_sort(self, other)
Sorting routine which allows to sort processes for comparison.

source code

identical_particle_factor(self)
Calculate the denominator factor for identical final state particles

source code

check_expansion_orders(self)
Ensure that maximum expansion orders from the model are properly taken into account in the process

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.

source code

__ne__(self, other)
x!=y
