The results and the perspectives of theoretical and experimental studies will represent a guideline of the formulation of an upgraded version of LEANNIS to be prepared for HadronPhysics3

  • As a starting point the ideas for (upgraded) research topics for LEANNIS-2 have to be discussed at the end of this LEANNIS Meeting, taking into account the anticipated outcome of LEANNIS till the beginning of the new project

LEANNIS Meeting, LNF, April 8-9, 2010

slide6

A fair way to discuss all options for this upgraded version will be chosen. I would like to collect updated versions of the different tasks as well as ideas for new tasks. We can do it via email. Finally we should have video/telephone conference and/or a meeting about the proposal for HP3 (meeting in Vienna? ).

LEANNIS Meeting, LNF, April 8-9, 2010

outlook and perspectives
Outlook and perspectives
  • Concerning the short term plan we have still 18 month till the end of HadronPhysics2 and accordingly LEANNIS

(i.e. Till end of December 2011)

  • The wok plan of LEANNIS was developed nearly 3 years ago - the time schedule of some experiments is changed due to delays , e.g. E17, AMADEUS,...
  • The running time of LEANNIS was reduced, so we have the chance with HP3 to go on with the original plan and defining new tasks in LEANNIS-2 (upgrading the project)
  • In June 2010 there will be an internal call in which LEANNIS is invited with deadline end of August 2010

LEANNIS Meeting, LNF, April 8-9, 2010

status and perspectives
Status and Perspectives
  • The program of this LEANNIS Meeting was a balanced mix of talks on the progress of different tasks and future perspectives
  • Many interesting topics for an upgraded LEANNIS network (LEANNIS-2 as working title) were presented – one has to select so to be compatible with the 3 years time line
  • The strengthen of the theory group with the participation of experts in the field (A. Gal and J. Mares) is highly welcomed and will certainly further enhance the theoretical part.

leannis time line
LEANNIS time line

Start

  • LEANNIS will run more than 1 year from now
  • Official project end in June 30, 2011, but will be extended till end of 2011
  • What can be finalized and what will be still topic in a possible continuation of LEANNIS?
  • New ideas and new possibilities have to be worked out quite fast
  • The efficient use of European research centers (accelerators), especially emergin FAIR is a strong point.
  • The use of non-European accelerators (J-PARC).

interplay theory experiment
Interplay theory-experiment
  • The field of strange exotic atoms and nuclei demands a joint effort of theory and experiment and will be a cornerstone in LEANNIS-2
  • Experiments can deliver input for detailed theoretical studies – the limited predictive power is calling for experiments
  • On the other hand new research topics arise from theoretical studies

LEANNIS Meeting, LNF, April 8-9, 2010

SOME ideas based on presentations at this meeting

LEANNIS Meeting, LNF, April 8-9, 2010

main topics for the future to be discussed
Main topics for the future? To be discussed
  • Strange kaonic atoms: higher precision, spectroscopy of heavier atoms, kaon mass
  • Direct experimental studies of subthreshold resonances (e.g. HADES) – this topic is presently not in the LEANNIS network included
  • Search for kaonic nuclei: some experiments will proceed others will be in the status of data analysis delivering important imput for theory

LEANNIS Meeting, LNF, April 8-9, 2010

outlook kaonic atoms
Outlook: kaonic atoms

Start

  • SIDDHARTA results on kaonic hydrogen and deuterium
  • The strong interaction observables (1s state shift and width) of kaonic deuterium is needed for the extraction of the scattering lengths
  • SIDDHARTA measured kaonic deuterium x-rays for the first time but the shift and width values still to be measured
  • The yield of the Lyman transitions is lower than anticipated , thus limiting the spectroscopy
  • SIDDHARTA results on kaonic helium-3 (gas) to be published soon
  • Precision experiment on kaonic helium-3 at J-PARC anticipated during the running time of LEANNIS

some open topics in reach of siddharta2 cf talks by tomo catalina
Some open topics in reach of SIDDHARTA2 (cf. talks by Tomo, Catalina)
  • High precision measurement of the kaonic deuterium Lyman x-ray spectrum, also possibility of more precise values of kaonic hydrogen
  • Detection of Lyman transitions in kaonic helium?
  • Study K-p  γΛgamma rays (proposed by S. Wycech)
  • Heavier kaonic atoms: completing the data set, improving precision, measurements of isotopes

LEANNIS Meeting, LNF, April 8-9, 2010

amadeus a laboratory for kaon reactions
AMADEUS a laboratory for kaon reactions
  • AMADEUS is expected to run after finishing the LEANNIS project
  • It will take advantage of the excellent KLOE apparatus combined with a gas target system and kaon trackers
  • The physics case :
    • Search for kaonic nuclear clusters in fully exclusive way
    • K reactions in helium isotopes
    • K scattering on different nuclei at low momenta taking advantage of the low momentum kaons from Phi-decay.

Start

  • FOPI result on the pp reactionat 3 GeVawaited
  • Pion inducedreactions (experiment in 2010)
  • AMADEUS experiment: Data analysis of KLOE data are progressing but the real experiment will excceed the LEANNIS time line (to be performed probably after 2012)
  • In-flight reaction at J-PARC (probably delayed depending on beam performance)
  • Searches at COSY TOF (pending because of beamline problems)

  • Needs detectorsystem

LEANNIS Meeting, LNF, April 8-9, 2010

kaonic nuclear clusters clarification needed
Kaonicnuclearclusters – Clarificationneeded

The open questions call for new data from experiments

using different reactions and providing detailled and reliable data concerning kaonic nuclear clusters and their properties.

The information coming from threshold data are crucial for theory.

LEANNIS Meeting, LNF, April 8-9, 2010

dafne
DAFNE
  • DAFNE at LNF is providing an unique source of low-energy monoenergetic kaons
  • The increase in luminosity (crab waist system) was reached and opens the way to high sensitivity experiments
  • The capability of using gas targets is a certain advantage for exotic atom research
  • SIDDHARTA2 and AMADEUS are very attractive for HP3

LEANNIS Meeting, LNF, April 8-9, 2010

slide24
GSI
  • The beams at GSI (proton, pion, heavy ion) are used for experiments in the field using detector systems FOPI, HADES.
  • What is the future in the light of the emerging FAIR research center?
  • As shown in the meeting many important experiments on kaonic nuclei and sub-threshold resonances can be performed.

leannis 2
LEANNIS 2
  • The scientific community of exotic atoms and nuclei with strangeness is small but very active in the field of hadron physics
  • Plans for efficient use of kaon sources (DAFNE in Europe, J-PARC in Japan) and (anti)proton beams in new experiments
  • It seems that there is more than enough topics to work out a program for a continuation of LEANNIS
  • However it has to be focussed on hot topics which are compatible with the time line of such a project

LEANNIS Meeting, LNF, April 8-9, 2010

time line
Time Line

2012

  • End of June 2010 internal call for proposals, LEANNIS is invited to deliver such a proposal
  • Deadline end of August 2010
  • September 2010 presentation of progress and proposals for HP3, selection by committee
  • LEANNIS-2 in HP3 could start in beginning 2012 (after finishing HP2) with a duration of 3 years

2014

LEANNIS Meeting, LNF, April 8-9, 2010

continuation of the network
Continuationofthe Network
  • After finishing LEANNIS strangeness physics with atoms and nuclei will certainly show progress but the research in this field will not be closed.
  • The predictive power of theory is limited and theory therefore calls or experimental results.
  • Is the scientific value high? Many activities are at different research centers are ongoing and the interest in the field can be shown in unbiased way. Therefore, it seems to be justified to continue with a network to maintain scientific contacts, foster the interest in the field, attract young scientists and spread results in the scientific community but also in the broad public.
