1. A. Nikitenko, IPPP+IC meeting, 28th May
SUSY Higgs in CMS
A. Nikitenko, IPPP+IC meeting, 28th May

2. Summary of PTDR CMS reach in MA-tanb
Since then curves were updated
including Db term (SUSY QCD corrections)
and variation of m – parameter:
two papers with George and Sven +CMS
people :
for neutral Higgs (2007)
for charged Higgs (2008)

3. from my talk on CMS Higgs meeting
Planning for “h->2t“ sub-group analyses with 200 pb-1: SUSY H->tt and H+->tn
from my talk on CMS Higgs meeting

4. SUSY H->2t at Tevatron: present and expectations
Present exclusion in MA-tan(b) expected

5. First try for low mass SUSY H->2t with 200 pb-1 at 10 TeV in CMS
Monica Acosta (IC): m+thad
Giuseppe Ceratti: e+m
tan(b) = stat. analysis is on the way,
Preliminary: CMS will be comparable or better

6. What to do with first 10-50 pb-1 ?
Measure Z->tt mass shape with Z->mm data
Measure OS/SS e/m+thad ratio and mass shape using non isolated leptons – QCD background
Measure e->thad fake rate using Z->ee data
With POGs:
e, m, thad ID (?)
thad fake rate
MET scale

7. Light charged Higgs: tt->WbH+b
Preliminary:
we expect to do better with 200 pb-1 at 10 TeV

8. What to do with first 10-50 pb-1 ?
CMS PAS TOP ,
100 pb-1 at 14 TeV
tt->WbH+b, lnb+tnb, LIP J. Varela, M. Gallinaro at al.
tt->WbH+b, qqb+tnb, HIP, R . Kinnunen, S. Lehti at al.
t+jets backgrounds using m->t replacement (see Matti Kortelinen talk on h->2t meeting 30th April)
jet->t fake rate
QCD bkg. with “random t jet” method
with TOP PAG
top mass reconstruction

9. IC people in SUSY Higgs physics
Inclusive H->tt
Monica Acosta + PhD student
Z->tt K. Petridis, writing PhD, will join H->tt
pp->bbH, H->tt and pp->bbZ
Anne-Marie Magnan + PhD student
D. Colling + A.N. – IC Higgs group coordinators

10. Input from theorists needed
Cross-sections at 10 TeV.
Branching ratios and masses from HeynHiggs
t->H+b branching (to be included in FeynHiggs)
Generators for SUSY gg->H (with b included in the loop) and pp->bbH (massive b)
