TheFifthHEIDELBERGInternationalConferenceonDarkMatterinAst- and
Particle Physics, DARK 2004, took place at Texas A&M
University, College Station Texas, USA, October 3-9, 2004. It was,
after Cape Town 2002, the second conference of this series held
outside Germany. The earlier meetings, starting in 1996, were held
in Heidelberg. Dark Matter is still one of the most exciting and
central ?elds of ast- physics, particle physics and cosmology. The
conference covered, as usual for this series, a large range of
topics, theoretical and experimental. Theoretical talks covered
SUSY/SUGRA phenomenology, which provides at present a preferred
theoretical framework for the existence of cold dark matter. Also
included were other possible explanations of dark matter such as
SUSY Q balls, exciting New Symmetries, etc. The most important
experiments in the underground search for cold and hot dark matter
were presented. Talks describing the current experimental dark
matter bounds, what might be obtained in the near future, and the
reach of future large (i.e. one ton) detectors were given. The
potential of future colliders to correlate accelerator physics with
dark matter searches was also outlined. Thus the reader will be
able to see the present status and future prospects in the search
for dark matter. The exciting astronomical evidence for dark matter
and corresponding observations concerning the Milky Way's black
hole, high-redshift clusters, wakes in dark matter halos were other
important topics at the conference.
Dark matter and dark energy are one of the central mysteries in
modern physics, although modern astrophysical and cosmological
observations and particle physics experiments can and will provide
vital clues in uncovering its true nature. The DARK 2009 Conference
brought together World's leading researchers in both astrophysics
and particle physics, providing an opportunity and platform to
present their latest results to the community. The topics covered
are wide-ranging, from terrestrial underground experiments to space
experimental efforts to search for dark matter, and on the
theoretical aspects, from the generating of a fifth family as
origin of dark matter, extra dimensions and dark matter to
non-standard Wigner classes and dark matter. One of the new
highlights was certainly a possible connection between a neutrino
mass as observed by nuclear double beta decay and the dark energy.
Highly important and relevant in its field, the book presents a
vital snapshot of the sometimes seemingly disparate areas of dark
matter research and offers an exciting overview of current ideas
and future directions.
The Fourth HEIDELBERG International Conference on Dark Matter in
Astro and Particle Physics, DARK2002, was held in Cape Town, South
Africa, in the period 4-9 February 2002. This majestic natural area
was the site of the first conference of this series (hosted since
1996 in Heidelberg) to be held outside of Germany. Dark Matter has
become one of the most exciting and central fields of as
trophysics, particle physics and cosmology. The conference covered,
as usual for this series, a large range of topics, theoretical and
experimental. Topics included Astronomical Evidence for Dark
Matter, the Cosmic Microwave Background, Supersymmetry, Inflation
and Dark Energy, Structure Formation, Hot and Cold Dark Matter, and
Ultrahigh Energy Cosmic Rays all of which were represented by
experts in the field. It was very nice to see again many of our
'old' friends in Dark Matter here in South Africa. The organizers
were very glad to see, in addition to world experts, the new
generation here. Many young participants gave very nice
professional talks during the conference. We are grateful to John
Ellis for doing an incredible job preparing his excellent summary
talk during the sessions. Some special interest and intensive
discussions were naturally raised by the first announcement of
terrestrial evidence for hot dark matter, obtained from neutrino
less double beta decay. This now adds to the evidence for cold dark
matter which we have from DAM A for several years already, and
which remained unchallenged up to now by other experiments.
Nuclear physics is presently experiencing a thrust towards
fundamental phy sics questions. Low-energy experiments help in
testing beyond today's stan dard models of particle physics. The
search for finite neutrino masses and neutrino oscillations, for
proton decay, rare and forbidden muon and pion de cays, for an
electric dipole moment of the neutron denote some of the efforts to
test today's theories of grand unification (GUTs, SUSYs,
Superstrings, ... ) complementary to the search for new particles
and symmetries in high-energy experiments. The close connections
between the laws of microphysics, astrophysics and cosmology open
further perspectives. This concerns, to mention some of them,
properties of exotic nuclei and nuclear matter, and star evolution;
the neutrino and the dark matter in the universe; relations between
grand unification and evolution of the early universe. The
International Symposium on Weak and Electromagnetic Interactions in
Nuclei (W.E.LN. 1986)' held in Heidelberg 1-5 July 1986, in
conjunction with the 600th anniversary of the University of
Heidelberg, brought together experts in the fields of nuclear and
particle physics, astrophysics and cosmol ogy."
Die letzten bei den Jahrzehnte haben eine explosive Entwicklung der
Teil und Kosmologie erlebt. Die Teilchenphysik erwies chenphysik,
Astrophysik sich als ein entscheidendes Mittel zum tieferen
Verstandnis des Universums. Das Aufkommen der Theorien der Grossen
Vereinigung der Krafte in der Teil chenphysik erlaubte, das fruhe
Universum bis zu den fruhesten Zeitpunkten zuruckzuverfolgen.
Umgekehrt treten in astrophysikalischen und kosmologi schen
Prozessen Energien auf, die man in Beschleunigern auf absehbare
oder besser unabsehbare Zeit nicht erreichen kann, und die die
Realisierung ei nes Teils der Fulle der exotischen
teilchentheoretischen Vorhersagen erlaubt haben konnten:
Baryogenese, Inflation, die Produktion exotischer Teilchen -
Monopole, kosmische Strings, Axionen und viele andere.
Supersymmetri sche Teilchen (Neutralinos) sind Kandidaten fur kalte
dunkle Materie, die die soeben der Beobachtung zuganglich gewordene
grossraumige Struktur des Universums und ihre Entstehung
verstandlich machen konnten. Neutrinos sind Kandidaten fur heisse
dunkle Materie. Eigenschaften von Neutrinos be einflussen die
Explosion der Supernovae. Astrophysikalische Neutrinoquellen helfen
bei der Bestimmung von Neutrino-Eigenschaften, die eine Schlussel
funktion fur die Struktur der Elementarteilchen-Theorien einnehmen.
Astro physikalisch erzeugte Axionen sondieren das starke CP-Problem
der QCD. Es entstand ein neues Forschungsgebiet, die
Teilchenastrophysik, in der man von zwei Seiten versucht, einigen
der fundamentalen Probleme der modernen Physik naherzukommen. Das
enorme Wachstum in diesem Bereich macht es - insbesondere fur den
Anfanger auf diesem Gebiet - zunehmend schwieriger, der Entwicklung
auf dem Wege uber die Fachliteratur zu folgen."
