Detailed Description

Calculate transverse jet profiles.

Calculate the differential and integral jet shapes in \(P_{\perp}\) for a given set of jets. This particular jet shape projection calculates jet shapes relative to jet centroids, using only the particles associated to each jet, for the hardest \( n \) jets.

The rapidity scheme ( \( \eta \) or \( y \)) has to be specified when invoking the constructor.

The differential jet shape around a given jet axis at distance interval \( r \pm \delta{r}/2 \) is defined as

\[\rho(r) = \frac{1}{\delta r} \frac{1}{N_\mathrm{jets}} \sum_\mathrm{jets} \frac{P_\perp(r - \delta r/2, r+\delta r/2)}{p_\perp(0, R)} \]

with \( 0 \le r \le R \) and \( P_\perp(r_1, r_2) = \sum_{\in [r_1, r_2)} p_\perp \).

The integral jet shape around a given jet axes until distance \( r \) is defined as

\[\Psi(r) = \frac{1}{N_\mathrm{jets}} \sum_\mathrm{jets} \frac{P_\perp(0, r)}{p_\perp(0, R)} \]

with \( 0 \le r \le R \) and \( P_\perp(r_1, r_2) = \sum_{\in [r_1, r_2)} p_\perp \).

The constructor expects also the binning in radius \( r \) to be supplied.

before()

bool Rivet::Projection::before ( const Projection & p ) const

inherited

Determine whether this object should be ordered before the object p given as argument. If p is of a different class than this, the before() function of the corresponding type_info objects is used. Otherwise, if the objects are of the same class, the virtual compare(const Projection &) will be returned.
