Jade-P0 3-jet resolution y3


Definition of the observable

$ y_3$ in the Jade algorithm in the P0-scheme is obtained following the procedure described in Sec. 15.1, but the definition of $ y_{ij}$ in (22) is replaced by (27)and the recombination is defined in ([*]).

Born event used for the analysis

The hard scale (Q) is taken to be the center-of-mass energy.

Elementary tests on the observable

Test result
check number of jets T
all legs positive T
globalness T

Single emission properties

leg $ \ell$ $ a_{\ell}$ $ b_{\ell}$ $ g_{\ell}(\phi)$ $ d_{\ell}$ $ \langle \ln g_{\ell}(\phi) \rangle$
1 1.000 $ 1.000 $ 1 1.000 0
2 1.000 $ 1.000 $ 1 1.000 0

Multiple emission tests

Test result
continuously global T
exponentiation (condition 1) T
exponentiation (condition 2a) F
exponentiation (condition 2b) T
exponentiation F
additivity F
eliminate subleading effects F
opt. probe region exists F

Information regarding the presence of possible zeros

leg 1 2
1 good zero good zero
2 good zero good zero

Classification of legs into divergent sequences with shared properties

Sequence number 1 has 2 legs
Legs in the sequence: 1 2
Orientation of the legs: 0 0
Type of zero: zt_unrecognised
Position of the divergence could not be determined

Since this observable does not exponentiate, multiple emission effects have not been computed.
