This is a copy of the diagram from Wikipedia. I produced this using codes developed by me as previously instructed here with other examples. — What to do when its 2 am around here, you are fresh but nowhere to go.

Higgs production, how its produced, one of the channels called Higgs-Strahlung

Here is the code:

% Feynman diagram

% Requires PGF >= 2.0









:Title: Higgs-Strahlung from Wikipedia



% Define styles for the different kind of edges in a Feynman diagram


photon/.style={decorate, decoration={snake,amplitude=1mm, segment length=4mm}, draw=cyan},

electron1/.style={draw=blue, thick, postaction={decorate},decoration={markings,mark=at position .55 with {\arrow[draw=red]{<}}}},

electron2/.style={draw=blue, postaction={decorate},decoration={markings,mark=at position .55 with {\arrow[draw=red]{>}}}},

electron3/.style={postaction={decorate}, draw=red, dashed, thick, decoration={markings,mark=at position .55 with {\arrow[draw=red]{}}}},




        % Set the overall layout of the tree

        level/.style={level distance=1.5cm},

        level 2/.style={sibling distance=2.6cm},

        level 3/.style={sibling distance=3cm}


%[level 1/.style={level distance=10mm},

%level 2/.style={level distance=5mm}]

\node (root)

child[grow =south west]{node{$f$} edge from parent [electron1]}

child[grow=north west]{node{$\bar{f}$} edge from parent [electron2]}

child[grow=right]{node [align=left]{W/Z}

edge from parent [photon]}

{child[grow=right]{edge from parent [photon] }


child[grow=south east]{ edge from parent [electron3]}

child[grow=north east]{ edge from parent [photon]}}


node at (root-3-1-1) {$H$}

%node at (root-3-1) {$W$}

node at (root-3-1-2) {$W/Z$}
