    After a long consultation process, the Kingdom of Bhutan finally adopted its very first constitution on 18 July 2008 (1). Heralded with great fanfare in the country itself as a modern, forward looking accomplishment set to help propel Bhutan towards a democratic society (2), the Constitution of the Kingdom of Bhutan is – from the point of view of international human rights law – a deeply disturbing document

    Understanding DsJ∗(2317)D_{sJ}^*(2317), DsJ(2460)D_{sJ}(2460)

    I briefly review the experimental observations concerning the charmed mesons DsJ∗(2317)D_{sJ}^*(2317), DsJ(2460)D_{sJ}(2460) and survey on some of the interpretations proposed in order to understand their nature. I present an analysis of their decay modes in the hypothesis that they can be identified with the scalar and axial vector sℓP=12+s_\ell^P={1 \over 2}^+ states of csˉc{\bar s} spectrum (Ds0∗D_{s0}^*, Ds1′D_{s1}^\prime). The method is based on heavy quark symmetries and Vector Meson Dominance ansatz. Comparison with present data supports the interpretation.Comment: LaTex, 10 pages.

    Multifrequency study of a new Hybrid Morphology Radio Source

    Hybrid Morphology Radio Sources (HyMoRS) are a class of radio galaxies having the lobe morphology of a Fanaroff-Riley (FR) type I on one side of the active nucleus and of a FR type II on the other. The origin of the different morphologies between FR I and FR II sources has been widely discussed in the past 40 years, and HyMoRS may be the best way to understand whether this dichotomy is related to the intrinsic nature of the source and/or to its environment. However, these sources are extremely rare (<1% of radio galaxies) and only for a few of them a detailed radio study, that goes beyond the morphological classification, has been conducted. In this paper we report the discovery of one new HyMoRS; we present X-ray and multi-frequency radio observations. We discuss the source morphological, spectral and polarisation properties and confirm that HyMoRS are intrinsically bimodal with respect to these observational characteristics. We notice that HyMoRS classification based just on morphological properties of the source is hazardous.Comment: 8 pages, 9 figures, accepted MNRA
