    Kolcu, Onur Buğra (Arel Author) --- Makale 70 yazarlıdır.We study the decays of the charmonium resonances J/? and ?(3686) to the final states ?-?¯+, ?(1385)±?¯(1385)± based on a single baryon tag method using data samples of (223.7±1.4)×106 J/? and (106.4±0.9)×106 ?(3686) events collected with the BESIII detector at the BEPCII collider. The decay ?(3686)›?(1385)±?¯(1385)± is observed for the first time, and the measurements of the other processes, including the branching fractions and angular distributions, are in good agreement with and much more precise than the previously published results. Additionally, the ratios B(?(3686)›?-?¯+)B(J/?›?-?¯+), B(?(3686)›?(1385)-?¯(1385)+)B(J/?›?(1385)-?¯(1385)+) and B(?(3686)›?(1385)+?¯(1385)-)B(J/?›?(1385)+?¯(1385)-) are determined

    We study the decays of J/ψ and ψ(3686) to the final states (1385)0( ¯ 1385)0 and 0 ¯ 0 based on a single baryon tag method using data samples of (1310.6 ± 7.0) × 106 J/ψ and (447.9 ± 2.9) × 106 ψ(3686) events collected with the BESIII detector at the BEPCII collider. The decays to (1385)0( ¯ 1385)0 are observed for the first time. The measured branching fractions of J/ψ and ψ(3686) to 0 ¯ 0 are in good agreement with, and much more precise than, the previously published results. The angular parameters for these decays are also measured for the first time. The measured angular decay parameter for J/ψ → (1385)0( ¯ 1385)0, α = −0.64 ± 0.03 ± 0.10, is found to be negative, different to the other decay processes in this measurement. In addition, the “12% rule” and isospin symmetry in the decays of J/ψ and ψ(3686) to ¯ and (1385)( ¯ 1385) are tested. © 2017 The Author(s). Published by Elsevier B.V.

    Publikowany artykuł Adama Kamińskiego, znakomitego paleografa i edytora staropolskich źródeł historycznych (1905–1981), omawia system skrótów paleograficznych stosowanych przez pisarzy sądu ziemskiego krakowskiego w najstarszej zachowanej księdze tego sądu w Polsce z lat 1374–1385, przechowywanej w Archiwum Narodowym w Krakowie pod sygn. 29/1/1. Autor porównuje go ze skrótami stosowanymi na Zachodzie Europy na podstawie podręczników paleografii i słowników skrótów. Wydawany obecnie tekst jest świadectwem wczesnych zainteresowań i studiów paleograficznych A. Kamińskiego, których wyniki nie mogły być wtedy opublikowane, głównie ze względu na ograniczone możliwości finansowe i techniczne ówczesnych archiwów państwowych. Stanowi jednak cenny i ciekawy, a przy tym nieznany przyczynek do badań nad kancelarią sądów ziemskich w Polsce. Adam Kamiński on the shorthand of the oldest Krakow land register (1374–1385) The article by Adam Kamiński, an outstanding palaeographer and editor of old-Polish historical sources (1905–1981), discusses the system of palaeographic shorthand used by scribes of the Krakow land court in the oldest preserved register of the court in Poland from the years 1374–1385, stored in the National Archives in Krakow with the reference number 29/1/1. The author compares it with the shorthand used in western Europe based on handbooks of palaeography and shorthand dictionaries. The current text is testimony to Kamiński’s early palaeographic interests and studies, whose results were not published at the time, mainly due to the limited financial and technical resources of the state archives. This represents a valuable and interesting, as well as an unknown, contribution to research into land court offices in Poland. KEY WORDS: shorthand, land register, palaeography, writing, Krakow land cour
