Constraining solar hidden photons using HPGe detector
R. Horvat, D. Kekez, M. Krcmar +2
In this Letter we report on the results of our search for photons from a U(1) gauge factor in the hidden sector of the full theory. With our experimental setup we observe the singl…
Hunting up low-mass bosons from the Sun using HPGe detector
R. Horvat, D. Kekez, M. Krcmar +2
In this experiment we aim to look for keV-mass bosons emitted from the Sun, by looking at a process analogous to the photoelectric/Compton effect inside the HPGe detector. Their co…
Search for solar hadronic axions produced by a bremsstrahlung-like process
D. Kekez, A. Ljubicic, Z. Krecak +1
We have searched for hadronic axions which may be produced in the Sun by a bremsstrahlung-like process, and observed in the HPGe detector by an axioelectric effect. A conservative…
Constraining theories of low-scale quantum gravity by non-observation of the bulk vector boson signal from the Sun
R. Horvat, D. Kekez, Z. Krecak +1
In this experiment we aim to detect Kaluza-Klein (KK) excitations of the bulk gauge field, emitted in a bremsstrahlung process on solar plasma constituents, by looking at a process…
Search for hadronic axions using axioelectric effect
A. Ljubicic, D. Kekez, Z. Krecak +1
We made a search for hadronic axions which could be emitted from the Sun in M1 transitions between the first 14.4 keV thermally excited and the ground state in Fe-57, and absorbed…
A Search For Solar Hadronic Axions Using Kr-83
K. Jakovcic, Z. Krecak, M. Krcmar +1
We introduce a new experimental method for solar hadronic axions search. It is suggested that these axions are created in the Sun during M1 transition between the first thermally e…
Search for solar axions using Li-7
M. Krcmar, Z. Krecak, A. Ljubicic +2
We describe a novel approach to the search for solar, near-monochromatic hadronic axions, the latter being suggested to be created in the solar core during M1 transitions between t…
Search for Solar Axions Using Fe-57
M. Krcmar, Z. Krecak, M. Stipcevic +2
We have made a search for Fe-57 gamma rays of energy 14.4 keV induced by resonant absorption of monochromatic solar axions, as proposed by Moriyama. The proposed axions are suggest…
