© 2022 authors. Published by the American Physical Society.The weak decays of doubly heavy ΞQQ baryon induced by flavor changing b→d and c→u flavor changing neutral current within the light-cone sum rules are studied. The sum rules are constructed and analyzed for the corresponding transition form factors using the parallel components of the light-cone distribution amplitudes for ΛQ baryon. Having the results for the form factors, the corresponding branching ratios for ΞQQ→ΛQl+l- decays are estimated. While the branching ratio due to b→d transition is around 10-9, in c→u transition case, it is found as around 10-13. Hence, Ξbb→Λbl+l- decay has the potential of being discovered at LHCb. However, Ξbb→Λbl+l- is difficult to be measured due to the extremely small values of obtained branching ratio. Our results on the branching ratio are also compared with the results of the light-front approach.

Determination of the spectroscopic parameters of beauty-partners of Tcc from QCD Alıyev, Tahmasıb; Savcı, Mustafa; Bilmiş, Selçuk (2022-04-01) © 2022 authors. Published by the American Physical Society.Motivated by the recent discovery of a new tetraquark Tcc+ state with two charm quarks and two light quarks by LHCb Collaboration, we calculate the spectroscopic parameters; namely, the mass and residues of beauty partners of Tcc+ within QCD sum rules. The obtained results are compared with the predictions of different approaches in the literature.
Final results on neutrino oscillation parameters from the OPERA experiment in the CNGS beam Agafonova, N.; et. al. (American Physical Society (APS), 2019-09-06) © 2019 authors. Published by the American Physical Society.The OPERA experiment has conclusively observed the appearance of tau neutrinos in the muon neutrino CNGS beam. Exploiting the OPERA detector capabilities, it was possible to isolate high purity samples of νe, νμ and ντ charged current weak neutrino interactions, as well as neutral current weak interactions. In this paper, the full dataset is used for the first time to test the three-flavor neutrino oscillation model and to derive constraints on the ...
Classification of permutation polynomials of the form x3g(xq-1) of Fq2 where g(x) = x3+ bx+ c and b,c∈Fq∗ Özbudak, Ferruh; Gülmez Temür, Burcu (2022-07-01) © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.We classify all permutation polynomials of the form x3g(xq-1) of Fq2 where g(x) = x3+ bx+ c and b,c∈Fq∗. Moreover we find new examples of permutation polynomials and we correct some contradictory statements in the recent literature. We assume that gcd (3 , q- 1) = 1 and we use a well known criterion due to Wan and Lidl, Park and Lee, Akbary and Wang, Wang, and Zieve.
Numerical heat transfer modelling of a centrifugal solar particle receiver Hiçdurmaz, Serdar; Johnson, Evan F.; Grobbel, Johannes; Amsbeck, Lars; Buck, Reiner; Hoffschmidt, Bernhard (2022-05-12) © 2022 Author(s).Solar particle receivers promise higher operating temperatures compared to molten salt-based receivers. The Discrete Element Method (DEM) tool LIGGGHTS is used to simulate the particle motion in a centrifugal solar particle receiver. A separate thermal model is developed in MATLAB, which uses the particle positions calculated with the DEM simulation. Heat transfer at the particle scale is accounted for with models of particle-particle conduction, particle-fluid- particle conduction, and a n...
Development of a three-dimensional basin model to evaluate the site effects in the tectonically active near-fault region of Gölyaka basin, Düzce, Turkey Yousefi-Bavil, Karim; KOÇKAR, MUSTAFA KEREM; Akgün, Haluk (2022-01-01) © 2022, The Author(s), under exclusive licence to Springer Nature B.V.The high seismicity and tectonic activity of the study area located in a near-fault region in Gölyaka, Düzce, results in a bedrock geometry highly complex in the sense of faulting and deformation. This makes this area very challenging in terms of a site response study that would aid seismic hazard assessment. This study develops a basin model to evaluate the site effects in the tectonically formed Plio-Quaternary fluvial sedimentary layer...
