Description

Dear Renjie,

Please see: http://arxiv.org/pdf/0809.4750.pdf

Eq. (8) and (9) describe the mapping between the
models.

Hi Stephen, Nishita,
I have a question about unparticle and LED implementation in Pythia8.
From manual: http://home.thep.lu.se/~torbjorn/pythia81html/Welcome.html
I find it is very close between the LED model and so-called unparticle model, I would like to know if
I simulate events with process of ExtraDimensionsLED:ffbar2GZ with following parameters:

processParameters = cms.vstring('ExtraDimensionsLED:ffbar2GZ = on',
'ExtraDimensionsLED:t = 0.5',
'ExtraDimensionsLED:n = 5',
'ExtraDimensionsLED:MD = 1000.',
'ExtraDimensionsLED:LambdaT = 1000.',
'5000039:m0 = 1200.',
'5000039:mWidth = 1000.',
'5000039:mMin = 1.',
'5000039:mMax = 13990.',
'23:onMode=off',
'23:mMin=50’,

Can I get an “equivalent" unparticle sample (ExtraDimensionsUnpart:ffbar2UZ),
with specific parameter space (dU, LambdaU, lambda) ? and vice versa.
Thanks ahead;
Ren-Jie
