Detailed Description

Container to store values of single quark distribution.

This class represents a quark distribution at a single kinematic point. For example, it can be GPD of a given type and specific quark flavor at some GPD kinematics.

Except the information on the assigned quark flavor, three values can be stored in this container: 1) value of the quark distributions, 2) value of the singlet combination and 3) value of the non-singlet combination. For the definition of singlet and non-singlet combinations see the documentation of QuarkDistribution::m_quarkDistributionPlus and QuarkDistribution::m_quarkDistributionMinus members. Note, that these combinations appear naturally in many GPD-related computations.

To see how this class can be used, analyze the following example:

//in code, e.g. in one of GPD modules, we calculate values of GPD H for up quarks at x and -x kinematics
double HuAtX = 2.34;
double HuAtmX = 1.23;
 
//calculate singlet and non-singlet combinations (note: definition is specific for given GPD type!)
double HuSinglet = HuAtX - HuAtmX;
double HuNonSinglet = HuAtX + HuAtmX;
 
//store my results in QuarkDistribution object
QuarkDistribution quarkDistribution(QuarkFlavor::UP, HuAtX, HuSinglet, HuNonSinglet);
 
//check what is inside
Partons::getInstance()->getLoggerManager()->info("example", __func__, ElemUtils::Formatter() << "My quark distribution contains: " << quarkDistribution.toString());

which gives via Logger:

20-05-2017 09:16:45 [INFO] (example::main) Quark distribution contains: u = 2.34
u(+) = 1.11
u(-) = 3.57

Check also the documentation of GPDResult and PartonDistribution classes, where QuarkDistribution objects are used extensively.

◆ m_quarkDistribution

double PARTONS::QuarkDistribution::m_quarkDistribution

private

Value of quark distribution.

◆ m_quarkDistributionMinus

double PARTONS::QuarkDistribution::m_quarkDistributionMinus

private

Value of non-singlet (minus) combination.

In GPD formalism it is C-odd combination of single type GPDs, e.g.:
\(H^{q(-)}(x, \xi, t) = H^{q}(x, \xi, t) + H^{q}(-x, \xi, t)\)
\(\tilde{H}^{q(-)}(x, \xi, t) = \tilde{H}^{q}(x, \xi, t) - \tilde{H}^{q}(-x, \xi, t)\)
and analogously for GPDs \(E\) and \(\tilde{E}\). See M. Diehl's https://arxiv.org/abs/hep-ph/0307382 Sec. 3.3.2 for more details.

◆ m_quarkDistributionPlus

double PARTONS::QuarkDistribution::m_quarkDistributionPlus

private

Value of singlet (plus) combination.

In GPD formalism it is C-even combination of single type GPDs, e.g.:
\(H^{q(+)}(x, \xi, t) = H^{q}(x, \xi, t) - H^{q}(-x, \xi, t)\)
\(\tilde{H}^{q(+)}(x, \xi, t) = \tilde{H}^{q}(x, \xi, t) + \tilde{H}^{q}(-x, \xi, t)\)
and analogously for GPDs \(E\) and \(\tilde{E}\). See M. Diehl's https://arxiv.org/abs/hep-ph/0307382 Sec. 3.3.2 for more details.
