Detailed Description

Class for collecting the basic objects related to the event shape.

This object is written by the EventShapeCalculator module, that stores here the quantities that require long calculations like the FW moments, the sphericity(-like) tensors and the shape axes (like thrust axis or jet axes). These quantities will be then used by the VaribaleManager functions to get the final EventShape variable, which are usually very simple to calculate. For example, the EventShapeCalculator will store here the Fox-Wolfram moments, while the ratios of them will be calculated on fly by the Variable Manager. We prefer this approach rather than storing every event shape variable directly here to keep a reasonably small data object, and making adding more variables easier.

All the quantities are defined and calculated in the center of mass frame.

The Event shape variables stored here can be divided into two classes: axis independent and axis-based. The first one are uniquely defined by the particles in the event, while the latter one require also a reference axis to be calculated.

The axis-independent quantities currently implemented are:

• sphericity tensor eigenvalues and eigenvectors
• Fow-Wolfram moments from 0 to 9

The axis-dependent quantities currently implemented are:

• Harmonic moments from 0 to 9
• Thrust
• Cleo cones All these quantities are can be stored in two versions:
• calculated respect to the e+e- collision axis (defined by the beam parameters)
• calculated respect to the thrust axis (calculated by the EventShapeCalculator module)
