Dear Colleagues,

The next Budapest-Debrecen-CERN talk of the Hungarian CMS 
group will be given on Monday, 28th May at 11:00 in the 
Media room of Wigner RCP, Budapest (KFKI Campus, Building 2) by

Jochen Schieck (HEPHY, Austrian Academy of Sciences):

"Search for Dark Matter with the CRESST III Experiment"

The quest for the particle nature of Dark Matter is one of 
the big open questions of modern physics. A well motivated 
candidate for Dark Matter is the so-called WIMP - a weakly 
interactive massive particle. Recently several theoretically 
well-motivated models with Dark Matter candidates in a mass 
region below the  WIMP mass-scale gained also a lot of 
interest, theoretically and experimentally.  The CRESST III 
(Cryogenic Rare Event Search with Superconducting 
Thermometers) experiment located at the Gran Sasso 
laboratory in Italy is optimised for the detection of the 
elastic scattering of these low mass Dark Matter particles 
with nuclei. CaWO4 crystals are used as detector medium and 
operated as cryogenic detectors at temperatures around 10mK. 
Sensitivity for nuclear recoils below 100eV was achieved, 
allowing for the exploration of new parameter space in the 
exclusion limit landscape. Besides the search for Dark 
Matter particles scattering with nuclei, we present a new 
search for so-called Dark Photons, also based on CRESST 
data.

As usual, the talk will be posted at the Indico category of 
our meetings [https://indico.cern.ch/category/8677/] and 
broadcasted via Vidyo in the virtual videoconferencing room 
"Budapest-Debrecen_meetings" (ext. 10593817), directly 
available from the Indico page. Everybody is welcome to 
join. Usually there are live H.323 connections among the 
videoconferencing rooms of the Institute of Nuclear Research 
(Atomki) in Debrecen, of the Department of Atomic Physics of 
ELTE, Budapest, and of Wigner RCP, Budapest.

See you (really or virtually) there:
