Plot the diffrentail cross section

Hi

You can include the unit conversion within luminosity value and calculate plot accordingly. Unit conversion is a universal transformation you can just multiply with the existing cross section and calculate the result in the way you want.

Cheers

Dear MadAnalysis team

I Need to plot the diffrentail with unit attobarn not picobarn in the
axe of y

You received this question notification because you are an answer
contact for MadAnalysis 5.

Please give me a example

Number of events per X GeV = xsec [pb] * 1000 * Lumi [1/fb] / X GeV

X is your bin size assuming you are plotting against mass or momentum etc.

Thank you
That give the diffrentail cross-section?

The differential cross-section is cross-section per bin.

How to get it

I gave you everything you need, i think you should read a bit more and think about it.

Hi

for my example

set un_evt.xsection = 0.07092
set main.lumi = (1/1000)*0.25
plot Y(z ) 12 0 3

Number of events per X GeV = xsec [pb] * 1000 * Lumi [1/fb] / X GeV

with X=0.25 GeV in my example

so Number of evants per X = xsec [pb] * 1000*(1/1000)*0.25/0.25
                                                    = xec[pb]

that don't give dsigma/dY (pb/GeV) ?

Y is rapidity it does not have units of GeV please read the manual and the reference card for the normal mode which can be found under docs folder. All your questions are answered in the documentations available online.

i don't found that in documentation please cite the reference

As i said docs folder in your local madanalysis folder or ma5 home page. There are ton of tutorials as well.

http://madanalysis.irmp.ucl.ac.be/wiki/FAQNormalMode#HowcanIcreateadifferentialcross-sectionplot
FAQ #3313: “Plot the diffrentail cross section”.

Thank you
In your example you set the lumi=1e-3*10 (10 is the bin size)
But you give me those relation
      Number of events per 10 GeV = xsec [pb] * 1000 * Lumi [1/fb] / 10 GeV
 So = xec[pb] isn't dsigma/dpT

Wath the difference between Number of events per bin size And Number of events per bin??
I don't understand

A bin has a size which the case of that example 10 GeV. Please read about histograms and how they are plotted. Your questions are not about MadAnalysis but about general knowledge of physics and can be found in any textbook or internet.

Yes I know Wath you said

I have in my histogram number of Z (particle) =number Of events

But Which relation we can use

number of events = sigma X lumi X 1000

Or

Number of events per X GeV = xsec [pb] * 1000 * Lumi [1/fb] / X GeV

Hi

Please learn what histogram is.
