void Herwig::AlpGenHandler::caldel_hvq | ( | ) | [private] |
c++ translation of subroutine of same name from alpsho.f.
Label all particles with status between ISTLO and ISTHI (until a particle with status ISTOP is found) as final-state, call calsim_m and then put labels back to normal. This version keeps only all IST=1 particles rejected by caldel as daughters of vetoed heavy-quark mothers: jets complementary to those reconstructed by caldel.
void Herwig::AlpGenHandler::caldel_m | ( | ) | [private] |
Deletes particles from partonsToMatch_ and particlesToCluster_ vectors so that these contain only the partons to match to the jets and the particles used to build jets respectively.
By and large the candidates for deletion are: vector bosons and their decay products, Higgs bosons, photons as well as _primary_, i.e. present in the lowest multiplicity process, heavy quarks and any related decay products.
void Herwig::AlpGenHandler::calini_m | ( | ) | [private] |
c++ translation of subroutine of same name from alpsho.f.
Initialize calorimeter for calsim_m and getjet_m. Note that because initialization is separte calsim_m can be called more than once to simulate pileup of several events.
void Herwig::AlpGenHandler::calsim_m | ( | ) | [private] |
c++ translation of subroutine of same name from alpsho.f.
Simple calorimeter simulation - assume uniform Y and phi bins.
virtual IBPtr Herwig::AlpGenHandler::clone | ( | ) | const [protected, virtual] |

Initialize this object after the setup phase before saving an EventGenerator to disk.
InitException | if object could not be initialized properly. |
Reimplemented from Herwig::ShowerHandler.
virtual void Herwig::AlpGenHandler::doinitrun | ( | ) | [protected, virtual] |
Initialize this object.
Called in the run phase just before a run begins.
Reimplemented from Herwig::ShowerHandler.
void Herwig::AlpGenHandler::doSanityChecks | ( | int | debugLevel | ) | [private] |
Allows printing of debug output and sanity checks like total momentum consrvation to be carried out.
debugLevel = -1, 0, ...5 = no debugging, minimal debugging, ... verbose.

c++ translation of subroutine of same name from alpsho.f.
Simple jet-finding algorithm (similar to UA1). Find highest remaining cell > ETSTOP and sum surrounding cells with -- DELTA(Y)**2+DELTA(PHI)**2 < RJET**2 , ET>ECCUT. Keep sets with ET>EJCUT and ABS(ETA)<ETACUT. The UA1 parameters are RJET=1.0 and EJCUT=5.0.

AlpGenHandler& Herwig::AlpGenHandler::operator= | ( | const AlpGenHandler & | ) | [private] |
