Detailed Description

Calculate the hemisphere masses and broadenings.

Calculate the hemisphere masses and broadenings, with event hemispheres defined by the plane normal to the thrust vector, $ \vec{n}_\mathrm{T} $.

Todo:
Allow axes to be defined by sphericity: superclass Thrust and Sphericity as AxisDefinition?
The "high" hemisphere mass, $ M^2_\mathrm{high} / E^2_\mathrm{vis} $, is defined as

\[ \frac{M^2_\mathrm{high}}{E^2_\mathrm{vis}} = \frac{1}{E^2_\mathrm{vis}} \max \left( \left| \sum_{\vec{p}_k \cdot \vec{n}_\mathrm{T} > 0} p_k \right|^2 , \left| \sum_{\vec{p}_k \cdot \vec{n}_\mathrm{T} < 0} p_k \right|^2 \right) \]

and the corresponding "low" hemisphere mass, $ M^2_\mathrm{low} / E^2_\mathrm{vis} $, is the sum of momentum vectors in the opposite hemisphere, i.e. $ \max \rightarrow \min $ in the formula above.

Finally, we define a hemisphere mass difference:

\[ \frac{M^2_\mathrm{diff} }{ E^2_\mathrm{vis}} = \frac{ M^2_\mathrm{high} - M^2_\mathrm{low} }{ E^2_\mathrm{vis}} . \]

Similarly to the masses, we also define hemisphere broadenings, using the momenta transverse to the thrust axis:

\[ B_\pm = \frac{ \sum{\pm \vec{p}_i \cdot \vec{n}_\mathrm{T} > 0} |\vec{p}_i \times \vec{n}_\mathrm{T} | }{ 2 \sum_i | \vec{p}_i | } \]

and then a set of the broadening maximum, minimum, sum and difference as follows:

\[ B_\mathrm{max} = \max(B_+, B_-) \]

\[ B_\mathrm{min} = \min(B_+, B_-) \]

\[ B_\mathrm{sum} = B_+ + B_- \]

\[ B_\mathrm{diff} = |B_+ - B_-| \]

Internally, this projection uses a Thrust or Sphericity projection to determine the hemisphere orientation.

const PROJ& addProjection ( const PROJ &  proj,
const std::string &  name 
) [inline, protected, inherited]

Register a contained projection. The type of the argument is used to instantiate a new projection internally: this new object is applied to events rather than the argument object. Hence you are advised to only use locally-scoped Projection objects in your Projection and Analysis constructors, and to avoid polymorphism (e.g. handling ConcreteProjection via a pointer or reference to type Projection) since this will screw up the internal type management.
