$\backslash frac\{d^2\backslash bold\{x\}\_\{a\}\}\{dt^2\}$

$\backslash sigma(p(P)p(P)\; \backslash to\; Y\; +\; X)\; =\; \backslash int\_0^1dx\_1\backslash int\_0^1dx\_2f\_1(x\_1)f\_2(x\_2)\backslash sigma(q\_1(x\_1P)q\_2(x\_2P)\; \backslash to\; Y)$

(this formula only works when split in two parts on CosmicVariance :) )

$x\; =\; \backslash frac\{P\_\{parton\}\}\{P\_\{proton\}\}$

$\backslash int\_0^1x[u(x)+\backslash bar\{u\}(x)+d(x)+\backslash bar\{d\}(x)+g(x)+...]dx=1$

$\backslash sigma\_i=\backslash frac\{N\_iA\_i\}\{L\}$

$A\_i=\backslash frac\{Nevent\_\{rec,i\}\}\{Nevent\_\{truth,i\}\}$
