Medium-indused modification of kaons spectra measured in SIDIS at HERMES

The predicted high sensitivity of the nuclear modification factor for K– in SIDIS due to the QCD based effect of medium-induced flavour conversion in the fragmentation function is studied at HERMES experiment. Unlike π+, π– and K+ nuclear modification factor for K– is assumed to increase at high value of Bjorken variable xB and a hadron fraction energy z. The experimental signature of this phenomenon is an enhanced K– nuclear modification factor compared with those of K+ for high xB and z range. The z spectra of nuclear attenuation ratios for charged kaons in different slices of xB extracted on Ne, Kr and Xe targets will be presented and discussed

THE INQUIRY’S QUEST TO SOLVE THE ARMENIAN QUESTION: 1917-1919

At the end of 1917 an official U.S. government body, known as The Inquiry, was created in order to prepare documents for the peace negotiations that were to follow World War I. The Inquiry was composed of around 150 academics and was directed by the presidential adviser Edward House. The suggestions made by the research body were incorporated into President Woodrow Wilson’s famous “Fourteen Points” which he delivered in the U.S. Congress on January 8th, 1918, defining the war aims of the United States during World War I and suggesting possible peace terms that would to follow the Great War. Point 12 of the “Fourteen Points” proclaimed that non-Turkish nations (which included Armenia) of the Ottoman Empire, should be given an opportunity for “autonomous development,” and accordingly The Inquiry was also tasked with defining the boundary of the future State of Armenia. In 1918 a number of reports were prepared by the research group which proposed the territory for the State of Armenia which extended from the Black Sea to the Mediterranean Sea, covering mostly Armenian Highland and the coastal areas of the above noted seas. Members of The Inquiry also suggested a union of the above noted territory with Eastern Armenia, a scheme that was officially presented in 1919 during the Paris Peace Conference by the American delegation

Medium-indused modification of kaons spectra measured in SIDIS at HERMES

The predicted high sensitivity of the nuclear modification factor for K$^−$ in SIDIS due to the QCD based effect of medium-induced flavour conversion in the fragmentation function is studied at HERMES experiment. Unlike π+, π− and K$^+$ nuclear modification factor for K$^−$ is assumed to increase at high value of Bjorken variable $x_B$ and a hadron fraction energy $z$. The experimental signature of this phenomenon is an enhanced K$^−$ nuclear modification factor compared with those of K$^+$ for high $x_B$ and $z$ range. The $z$ spectra of nuclear attenuation ratios for charged kaons in different slices of $x_B$ extracted on Ne, Kr and Xe targets will be presented and discussed

Medium-induced modification of kaons spectra measured in SIDIS at HERMES

The predicted high sensitivity of the nuclear modification factor for $K^-$ in SIDIS in respect to the medium-induced flavour conversion is studied at HERMES experiment. Unlike $\pi^+$, $\pi^-$ and $K^+$ nuclear modification factor for $K^-$ is assumed to increase at high value of Bjorken variable x and a hadron fraction energy z. The experimental signature of this phenomenon is an enhanced $K^-$ yields compared with those of $K^+$ for high Bjorken-x and z range. This is consequence of parton energy loss of the leading quarks. The Bjorken-x spectra of nuclear attenuation ratios for charged pions and kaons will be presented in different slices of z extracted on Ne, Kr and Xe targets

Beam-helicity asymmetries for single-hadron production in semi-inclusive deep-inelastic scattering from unpolarized hydrogen and deuterium targets

A measurement of beam-helicity asymmetries for single-hadron production in deep-inelastic scattering is presented. Data from the scattering of 27.6 GeV electrons and positrons off gaseous hydrogen and deuterium targets were collected by the HERMES experiment. The asymmetries are presented separately as a function of the Bjorken scaling variable, the hadron transverse momentum and the fractional energy for charged pions and kaons as well as for protons and anti-protons. These asymmetries are also presented as a function of the three aforementioned kinematic variables simultaneously

Measurement of the Ωc0\Omega_c^0 lifetime at Belle II

We report on a measurement of the $\Omega_c^0$ lifetime using $\Omega_c^0 \to \Omega^-\pi^+$ decays reconstructed in $e^+e^-\to c\bar{c}$ data collected by the Belle II experiment and corresponding to $207~{\rm fb^{-1}}$ of integrated luminosity. The result, $\rm\tau(\Omega_c^0)=243\pm48( stat)\pm11(syst)~fs$, agrees with recent measurements indicating that the $\Omega_c^0$ is not the shortest-lived weakly decaying charmed baryon
