Preliminary!
New interference weight in PHOTOS
comparison with the same conditions as in paper
"Radiative Corrections in K0_l3 Decays", by Troy C. Andre, hep-ph/0406006 v2,
figure 8.
We compare version of PHOTOS as until December 2004 and the new version (under study) where the interference weight (formula (17) from CPC 79 (1994), 291.
It looks that interference weight removes differences completely.
This interference weight, until now, was present only for Z decays. Thanks to work for W decays in 2003, it was now straightforward to implement.
WARNING! The new interference weight is not yet available in the official PHOTOS release
- This is as figure 8(a)
- This is as figure 8(b):
- This is as figure 8(c)
- This is as figure 8(d)
- This is as figure 8(c) but comparison of first-order PHOTOS with interference weight
and exponentiated PHOTOS (also with interference). In this case e Egamma denotes
the sum of energy of all photons.

- This is as figure 8(d) but comparison of first-order PHOTOS with interference weight
and exponentiated PHOTOS (also with interference). In this case e Egamma denotes
