ALEPH Higgs boson searches 
for the LEP Higgs Working Group


Here you can find the code to run the ALEPH inputs subroutine.
It contains the ALEPH search results for Higgs bosons up to ECM=210 GeV.

The current version is version 4.00 (released May 28, 2002). All the ALEPH data collected in 2000, for SM & MSSM neutral Higgs searches is included.

NEW (May/02): released the final fermiophobic Higgs inputs (see mini-update links below).

NEW (May/02): released the preliminary version of final SM/MSSM Higgs inputs.

The FORTRAN code. (Please use Shift+Left mouse to save.)

Description of the input/output arguments of subroutine a_inputs(...).

List of the files that you need to compile for regular running.

List of the files that you need to compile for tail test running.
