Top Processes
Different ways to produce top quarks, singly or in pairs.
Top:all
On
Off
(
default =
off
)
Common switch for the group of top production.
Top:gg2ttbar
On
Off
(
default =
off
)
Scatterings
g g -> t tbar
. Code 601.
Top:qqbar2ttbar
On
Off
(
default =
off
)
Scatterings
q qbar -> t tbar
by gluon exchange. Code 602.
Top:qq2tq(t:W)
On
Off
(
default =
off
)
Scatterings
q q' -> t q''
by
t
-channel exchange of a
W^+-
boson. Code 603.
Top:ffbar2ttbar(s:gmZ)
On
Off
(
default =
off
)
Scatterings
f fbar -> t tbar
by
s
-channel exchange of a
gamma^*/Z^0
boson. Code 604.
Top:ffbar2tqbar(s:W)
On
Off
(
default =
off
)
Scatterings
f fbar' -> t q''
by
s
-channel exchange of a
W^+-
boson. Code 605.
Top:gmgm2ttbar
On
Off
(
default =
off
)
Scatterings
gamma gamma -> t tbar
. Code 606.
By default top always decays to a
W
and a down-type quark. It is possible to switch on the
t -> H+ b
decay mode. Note that its partial width is calculated using the
tan(beta)
value stored in
HiggsHchg:tanBeta
, so that it can be used without having to read in a SUSY parameter file. For the
H+
to decay also
Higgs:useBSM = on
is necessary.
