Mixing and CPV in charm hadrons at LHCb

LHCb continues to expand its world-leading sample of charmed hadrons collected during LHC's Run 1 (2010-2012) and Run 2 (2015-present). This sample is yielding some of the most stringent tests of the Standard Model understanding of charm physics. This includes precise measurements of the neutral D-meson mixing parameters and some of the most sensitive searches for direct and indirect CP violation in charm interactions.Comment: 6 pages, 1 figure, presented at 21st Particles and Nuclei International Conference 2017 (PANIC 2017

Search for the 4He-eta bound state in dd->(4He-eta)_{bound}->3He n pi0 and dd->(4He-eta)_{bound}->3He p pi- reactions with the WASA-at-COSY facility

In November 2010, the search for the 4He-{\eta} bound state was per formed with high statistics and high acceptance with the WASA-at-COSY facility using a ramped beam technique. The signature of eta - mesic nuclei is searched for in the measured excitation functions for the two reaction channels: dd ->3He n pi0 and dd ->3He p pi- near the eta production threshold. This report includes the description of the experimental method and the status of the data analysis.Comment: 4 page

Luminosity determination for the deutron-deutron reactions using free and quasi-free reactions with WASA-at-COSY detector

Two methods of the luminosity determination for the experiment performed by WASA collaboration to search for $^{4} {-0.03cm}{He}$-$\eta$ bound state are presented. During the measurement the technique of continous change of the beam momentum in one accelerator cycle (called ramped beam) was applied. This imposes the requirement to determine not only the total integrated luminosity, but also its variation as a function of the beam momentum.Comment: Symposium on Applied Nuclear Physics and Innovative Technologies, Krakow (Poland), 24-27.09.201

Search for eta-mesic helium using the WASA-AT-COSY detector

We conduct a search for the 4He-eta bound state with the WASA-at-COSY facility via the measurement of the excitation function for the reaction dd->3Heppi-. In first experiment performed in June 2008, we used COSY deuteron beam with a slowly ramped beam momentum corresponding to a variation of the excess energy for the 4He-eta system from -51.4 MeV to 22 MeV. Here we report on the status of the measurement and the data evaluation.Comment: Presented at Symposium on Meson Physics: extended COSY-11 collaboration meeting, Cracow, Poland, 1-4 Oct 2008, 8 pages, 5 figures

Search for eta-mesic nuclei with WASA-at-COSY

We search for an evidence of eta-mesic He with the WASA detector. Two dedicated experiments were performed at the Cooler Synchrotron COSY-Juelich. The experimental method is based on the measurement of the excitation functions for the two reaction channels: dd->3Heppi- and dd->3Henpi0, where the outgoing N-pi pairs originate from the conversion of the eta meson on a nucleon inside the He nucleus.In this contribution, the experimental method is shortly described and the current status of the analysis is presented.Comment: 5 pages, 2 figure

Search for the eta-mesic Helium bound state with the WASA-at-COSY facility

We performed a search for 4He-eta bound state with high statistics and high acceptance with the WASA-at-COSY facility using a ramped beam technique. The signature of eta-mesic nuclei is searched for in dd -> 3Henpi0 and dd -> 3Heppi- reactions by the measurement of the excitation functions in the vicinity of the {\eta} production threshold. This paper presents the experimental method and the preliminary results of the data analysis for dd -> 3Henpi0 process.Comment: Proceedings from the 12th International Conference on Nucleus-Nucleus Collisions (NN2015), Catania 2015, June 21-2

Shaping the Jewish Enlightenment: Solomon Dubno (1738-1813), an Eastern European Maskil

This thesis concerns the life and literary output of Solomon ben Yoel Dubno (1738–1813), a Polish-Jewish grammarian and poet who was active in Amsterdam and Berlin. He became renowned for his work with Moses Mendelssohn on Sefer netivot ha-shalom (also known as Biur), a German translation of the Pentateuch, which was accompanied by a commentary in Hebrew and Masoretic emendations. // The thesis aims at recognising the understudied role that Eastern-European Jews played in the literature of the early Jewish Enlightenment (Haskalah). It adopts the literary and scholarly works of Solomon Dubno as a case study. Despite the fact that he was a key contributor to one of the signature publications of the early German Haskalah, Sefer netivot ha-shalom, he has been, to a great extent, ignored by the academic scholarship. // The thesis begins with an analysis of the background and goals of the Jewish Enlightenment, the role of Eastern-European Jews in shaping the Haskalah, as well as the frameworks within which historians have perceived Dubno’s work. Next, it examines the contents of Dubno’s private library, which were published as a booklist in 1771 and in a public auction catalogue in 1814, and interprets them as an ‘intellectual map’ of a Polish maskil who moved to Western Europe. Subsequently, it discusses Dubno’s work on the biblical commentary and his correspondence with Mendelssohn regarding the publication of the Biur. Dubno’s linguistic worldview is presented from a number of perspectives, starting from his approach towards Hebrew as a Jewish cultural legacy and the holy tongue, and ending in his emphasis on the importance of studying grammar and preserving the purity of the Hebrew language. Finally, the thesis analyses poems and belles-lettres that Dubno composed in Hebrew to demonstrate that this language was still appropriate for artistic expression
