1 Subjet Z distribution with different multiplicity and mean pt

Background and Hybrid Spectrum w and w/o background substraction

the first two plots is pure toy background spectrum

the last two plots is hybrid spectrum.

Background density

the shape of rho distribution like a gauss, after fit with the gauss ,we get the mean value and rms of the shape, on the right is the fit for mean value and rms of rho

<rho>= a*multiplicity density* meanpt +b

a=0.994024 +/- 0.00229552,

b= -0.333886 +/- 0.495517

rms= a*sart(multiplicity density)* meanpt +b

a=0.513158 +/- 0.0647313

b=0.513158 +/- 0.0647313

Subjet Z distribution with different multiplicity and mean pt in pure background condition

This four plots ,the Up left plot is the inclusive subjet z possibility distribution the up right plot is the leading subjet z possibility distribution

the down left plot is the mean value of inclusive z depend on jet pt ,the down right plot is the mean value of leading subjet z depend on jet pt.

Mult: double means multiplicity is 1914*2, half means multiplicity is 1914/2 , normal means multiplicity is 1914.

Subjet Z distribution with different multiplicity and mean pt in hybrid condition

This four plots ,the Up left plot is the inclusive subjet z possibility distribution the up right plot is the leading subjet z possibility distribution

the down left plot is the mean value of inclusive z depend on jet pt ,the down right plot is the mean value of leading subjet z depend on jet pt.

2 The pt and z difference in leading subjet and sub-leading subjet

The pt and z difference in leading subjet and sub-leading subjet in pure background condition

the up left plot is the pt difference between leading subjet and subleading subjet and the up right is the z difference between leading and subleading subjet.

the down left plot is the mean pt difference between leading subjet and subleading subjet and the down right is the mean z difference between leading and subleading subjet.

The pt and z difference in leading subjet and sub-leading subjet in Hybrid condition

the up left plot is the pt difference between leading subjet and subleading subjet and the up right is the z difference between leading and subleading subjet.

the down left plot is the mean pt difference between leading subjet and subleading subjet and the down right is the mean z difference between leading and subleading subjet.

3 Number of subjet depend on Z

Number of subjet depend on Z in pure bacground condition

the upper left is the number of subjet distribution ,the uper right is the mean number depend on jet pt, and the down left is the mean z depend on number of subjet .

Number of subjet depend on Z in hybrid condition

the upper left is the number of subjet distribution ,the uper right is the mean number depend on jet pt, and the down left is the mean z depend on number of subjet .
