Hi,

My name is Gerhard Brandt. I am a PhD in particle physics currently at DESY, Hamburg.

Besides just adding some comments and minor edits, i am interested especially in

• particle physics, particle detectors, particle accelerators (i guess you guessed that already ...)
• Memes in pop culture (especially if they are crossing several categories.)
• Electronic Music.

Actually i am interested in a great deal more subjects, but these are the ones where i am most likely to contribute.

$\nu ^{*}\rightarrow \nu \gamma$ $\nu ^{*}\rightarrow \nu Z$ $\nu ^{*}\rightarrow eW_{\hookrightarrow qq}$

Some QCD formula i hope to evolve into an article later

${\frac {\mathrm {d} \sigma }{\mathrm {d} x\mathrm {d} y}}={\frac {4\pi \alpha ^{2}s}{Q^{4}}}[xy^{2}F_{1}+(1-y)F_{2}]$ with

• $F_{1}=MW_{1}\qquad F_{2}=\nu W_{2}$

Splitting functions

$P_{qq}={\frac {4}{3}}({\frac {1+z^{2}}{1-z}})$

$P_{gq}={\frac {4}{3}}({\frac {1+(1-z)^{2}}{z}})$

$P_{qg}={\frac {1}{2}}(z^{2}+(1+z)^{2})$

$P_{gg}=6({\frac {1-z}{z}}+{\frac {z}{1-z}}+z(1-z))$
