Scaling methods

Scaling methods

  • Overall method:

  • Main idea of scaling methods is:

  • C(E) is obtained in 5 different ways:

  • From horn-off data, Ecut < E < Ehigh

  • From horn-off data, Elow < E < Ecut

  • From horn-off data, all energies

  • From horn-on data, E > Ehigh

  • From horn-on data, all energies (since

  • for )


Scaling methods

n from m+, MC

Scaling method 1: L010000 data/MC ratio, Ecut < E < Ehigh

data

Scaled MC, no m+

data/MC L010000

Scaling methods

n from m+, MC

Scaling method 2: L010000 data/MC ratio, 4 < E < Ecut

data

Fit methods

  • Used same procedure as Zarko & Rustem showed in Boston, i.e. Mega Fit such that:

  • Parameterize fluka p- yields.

  • 6 parameters to distort pt-xf p- distributions.

  • 2 parameters for kaons.

  • No Zbeam parameters, except for POT

  • Difference lies in that only regions with no m+ contributions are fit. Three separate fits were performed:

  • le010z000i (all E) & le010z185i (with E>Ecut)

  • le010z185i (with E>Ecut)

  • le010z000i (all E)


Scaling methods

Fit 1: le010z185i (E>Ecut) & le010z000i (all E)

le010z185i

le010z000i


Scaling methods

Fit 2: le010z185i (E>Ecut)

le010z185i


Scaling methods

Fit 3: le010z000i (all E)

le010z000i


Scaling methods

Predicting from the three fits:


Scaling methods

Scaling methods

n from m+, MC

Fit 2: le010z185i (E>Ecut)

data

Fit MC, no m+

MC (no m+)

Fit MC (no m+)

data-Fit MC


Scaling methods

n from m+, MC

Fit 3: le010z000i (all E)

MC (no m+)

Fit MC (no m+)

data

Fit MC, no m+

Scaling methods

n from m+ decay candidates

n from m+ decay candidates

Summary of Results

Expected to be negative

Should be ~0 if data/MC from horn-off is trust worthy in this region

Should be 0 by construction

Should be real nubars from m+
