Brief history of hep in austria
Brief History of HEP in Austria

1954: Foundation of CERN

1959:Austria becomes Member of CERN

1959-66: Small group at the Vienna University analyzing photoplates from

nuclear reactions, later analyzing bubble chamber pictures from CERN

1966:Institute for High Energy Physics of the Austrian Academy was founded..

With groups for “counter” expts., bubble chamber expts., theory, electronics,

mechanical workshop.

Institute was then involved in various experiments at the ISR and SPS,

and in a series of bubble chamber experiments

also experiment in Serpukhov

1968:Exp. group in Innsbruckcollaborates with Vienna in bubble chamber expts.

1978: Institute joins UA1 collider exp., 1983: discovery of W and Z bosons

1984-->: Vienna participates in DELPHI at LEP, since 1992 in NA48 (CP violation

in K0), since 1992 in CMS at LHC

since 2001 BELLE at KEK(Japan)

Innsbruck: ALEPH at LEP, ATLAS at LHC

Institute for

High Energy Physics





  • Only two experimental groups (Vienna + Innsbruck)

  • Experimental high energy physics is rather concentrated at the Institute

  • for High Energy Physics of the Academy of Sciences, Vienna

  • since 1995 no funding of experimental HEP by the Research Council

Funding of hep
Funding of HEP in NA48 (CP violation

  • Institute for HEP of the Academy of Sciences, Vienna:

  • funded by the Academy (Personnel + Material).

  • The Academy of Sciences is an autonomous institution

  • receiving a total budget for ~15 institutes from the Ministry

  • of Research

  • Experimental HEP group, Univ. of Innsbruck:

  • Material costs funded by the Ministry

  • Theory groups at the Universities (Vienna. Graz, Innsbruck)

    supported by the Research Council (FWF)

Funding of hep1
Funding of HEP in NA48 (CP violation

Until 1995: Experimental HEP was also supported by the in addition Research Council

1995: Decision by the Research Council to not support anymore

exp. HEP !

Reasons: “Big science”, HEP does not fit into the reviewing system.

“If Austria is member of CERN, the Ministry should (directly)

provide the means for participating in the CERN program”.

Since 1995, direct funding from Ministry worked so far for

NA48, the LEP experiments DELPHI and ALEPH, and the

MoU for CMS and ATLAS construction and the

MoU for maintenance..

NA48 Experiment(CP violation in the - system)

  • Main goal:Precision measurement of /  direct CP violation,

  • Re (/) = (14.7 ± 2.2) . 10-4, Phys.Lett. B544 (2002) 97

  • 2002: Na48/1: high intensity beam:  rare decays,

  • first observation of  π0e+e-

  • (information on ‘indirect’ CP violation in )

  • 2003: Na48/2: K beam:  measurement of CP violation in K

  • charge asymmetry K    

  • Contributions by the Institute:

  • Electronics for / tagging system

  • Trigger electronics neutral particles

  • Software

  • Physics analysis

Belle experiment

Experiment at “B-Factory”, KEK, Japan in NA48 (CP violation

BELLE Experiment

joined it in 2001 with the intention to participate in a running experiment

Goal: Precise measurement of CP violation in B decays

 Test of CKM matrix

  • Contributions by the Institute:

  • Read-out and trigger electronics for new inner Si-tracker

  • Physics analysis: determination of Vub of CKM matrix

Cms experiment at lhc

CMS Trigger: in NA48 (CP violation

Funding of cms by the ministry
Funding of CMS by the Ministry in NA48 (CP violation

Memorandum of Understanding (MoU) for CMS construction:

1996 – 2010: 4500 kCHF

already paid (1996 – 2003): 3091 kCHF

Memorandum of Understanding (MoU) for Maintenance & Operation:

2001 – 2003: 46.077 kCHF

Next e e linear collider
Next e in NA48 (CP violation-e+ Linear Collider

  • Active participation in ECFA Workshops on Physics and Detectors at a Linear Collider in two areas:

  • Phenomenology of supersymmetry

  • Robust vertex search and fitting methods

Conclusions in NA48 (CP violation

•Experimental HEP strongly centralized in the Institute of High Energy Physics of the Academy of Sciences in Vienna

• only oneuniversity institute in Innsbruck

• no chair in HEP experimental physics in Vienna

•HEP community small in comparison to other small member states

• community more or less constant, substantial fraction close to retirement

• problems in getting students

(reasons: no university institute in Vienna, big time interval between LEP and LHC,

competition from other fields)

•Budget more or less constant, no increase in sight, HEP no ‘priority’

• without additional direct funding by Ministry participation in CMS impossible (MoU for construction, for maintenance & operation; MoU for computing still to be negotiated)

•Doctoral student programme for technology crucial
