New Particles from Belle

I report recent results on hidden charm spectroscopy from Belle. These include: observation of a near-threshold enhancement in the omega-J/psi invariant mass distribution for exclusive B-->K omega J/psi decays; evidence for the decay X(3872)-->pi+pi-pi0 J/psi, where the pi+pi-pi0 invariant mass distribution has a strong peak between 750 MeV and the kinematic limit of 775 MeV, suggesting that the process is dominated by the sub-threshold decay X-->omega J/psi; and the observation of a peak near 3940 MeV in the J/psi recoil mass spectrum for the inclusive continuum process e+e- --> J/psi X. The results are based on a study of a 287 fb-1 sample of e+e- annihilation data collected at center- of-mass energies around the Upsilon(4S) in the Belle detector at the KEKB collider.Comment: 10 pages 12 figures.

Sengkarut Resistensi Pembangunan Jakarta: Dinamika Sinergisitas Pembangunan antara Kepentingan Pemerintah dengan Masyarakat

Pembangunan nasional pada dasarnya sangat membutuhkan kesinergian antara masyarakat dan Pemerintah. Masyarakat adalah pelaku utama dalam pembangunan dan Pemerintah berkewajiban untuk mengarahkan, membimbing, serta menciptakan suasana yang menunjang. Kegiatan masyarakat dan kegiatan Pemerintah harus saling menunjang, mengisi, dan melengkapi dalam mewujudkan pembangunan nasional. Namun, implementasi pembangunan yang digencarkan pihak-pihak tertentu kerap tidak menemui titik temu dalam menyelaraskan dua kepentingan yang berbeda, yaitu pihak Pemerintah dan masyarakat. Karena kepentingan yang dirasa berbeda inilah masyarakat menolak pembangunan yang dirasa \u27mengoyak\u27 kepentingan mereka. Penolakan inilah yang diwujudkan dalam resistensi. Pola pembangunan yang bersifat top-down sudah lama dan masih cenderung diterapkan di Indonesia. Pembangunan top-down ini didasarkan pada perencanaan elitis yang sering mengabaikan dan mengeksklusi kepentingan kelas bawah. Hingga saat ini, Indonesia masih mengalami berbagai dinamika pembangunan yang dilakukan berbagai pihak di berbagai wilayah dan daerah yang kerap terjadi, penggusuran mengatasnamakan kepentingan umum dan berdalih demi pembangunan. Contohnya, di Jakarta, dalam setahun tidak hanya ada satu, dua, tetapi bahkan belasan kasus penggusuran. Berdasarkan catatan Lembaga Bantuan Hukum Jakarta, terjadi 113 kasus penggusuran pada tahun 2015

EXAMINING THE INFLUENCE OF PARENTS, TEACHERS, AND NEIGHBORHOOD SAFETY ON AFRICAN AMERICAN ADOLESCENTS’ MOTIVATION AND ACHIEVEMENT

Guided by the theoretical frameworks of Baumrind’s parenting style theory, interpersonal expectations, Self Determination Theory, and self-efficacy, this study examines factors that influence African American students’ GPA and motivation, specifically associations between parents’ and teachers’ control, warmth, and educational expectations and African American adolescents’ GPA, self-efficacy, and intrinsic motivation were examined. The moderating effects of neighborhood safety on the aforementioned associations were also assessed. Using data from the Educational Longitudinal Study of 2002, this study found that parents’ warmth and expectations were positive predictors of all educational variables, while parents control was a negative predictor of GPA and intrinsic motivation. Teachers’ warmth was a positive predictor of GPA and intrinsic motivation, and teachers’ expectations were positive predictor of self-efficacy. Lastly, teachers’ control was a positive predictor of self-efficacy. Neighborhood safety did not moderate associations. Findings suggest that African American students’ academic development can be enhanced by interventions that target relational interactions

The PTI Carbon Star Angular Size Survey: Effective Temperatures and Non-Sphericity

We report new interferometric angular diameter observations of 41 carbon stars observed with the Palomar Testbed Interferometer (PTI). Two of these stars are CH carbon stars and represent the first such measurements for this subtype. Of these, 39 have Yamashita (1972,1975) spectral classes and are of sufficiently high quality that we may determine the dependence of effective temperature on spectral type. We find that there is a tendency for the effective temperature to increase with increasing temperature index by ~120K per step, starting at T_EFF ~= 2500K for C3,y, although there is a large amount of scatter about this relationship. Overall, the median effective temperature for the carbon star sample is found to be 2800 +- 270K, and the median linear radius is 360 +- 100 R_SUN. We also find agreement on average within 15K with the T_EFF determinations of Bergeat (2001,2002a,b), and a refinement of carbon star angular size prediction based on V & K magnitudes is presented that is good to an rms of 12%. A subsample of our stars have sufficient {u,v} coverage to permit non-spherical modeling of their photospheres, and a general tendency for detection of statistically significant departures from sphericity with increasing signal-to-noise of the interferometric data is seen. The implications of most - and potentially all - carbon stars being non-spherical is considered in the context of surface inhomogeneities and a rotation-mass loss connection.Comment: 59 pages, 15 figures, 6 tables; accepted for publication in Ap

Supersymmetric Contributions to Bs->K+K-

Inspired by the existing calculation of B->piK decays in supersymmetry (SUSY), we evaluate the dominant SUSY contributions to Bs->K+K-. We show that the observables of this process can be significantly modified in the presence of SUSY. In particular, the branching ratio can be increased considerably compared to the prediction of the standard model (SM). The effect is even more dramatic for the CP-violating asymmetries A_dir and A_mix. These asymmetries, expected to be small in the SM (A_dir is predicted to take only positive values), change drastically with SUSY contributions. The measurement of these observables can therefore be used to detect the presence of physics beyond the SM, and put constraints on its parameters.Comment: 17 pages, 2 figures.

A Uniform Description of the States Recently Observed at B-factories

The newly found states Y(4260), Y(4361), Y(4664) and Z$^\pm$(4430) stir broad interest in the study of spectroscopy in a typical charmonium scale. The Y(4260) which was observed earlier has been interpreted as hybrid, molecular state, and baryonium, etc. In this note we show for the first time that these new structures, which are hard to be interpreted as charmonium states, can be systematically embedded into an extended baryonium picture. According to this assignment, the so far known characters of these states are understandable. And, in the same framework, we make some predictions for experimenters to measure in the future.Comment: 6 pages in Latex. to appear in J.Phys.

Dynamical mass of the O-type supergiant in Zeta Orionis A

A close companion of Zeta Orionis A was found in 2000 with the Navy Precision Optical Interferometer (NPOI), and shown to be a physical companion. Because the primary is a supergiant of type O, for which dynamical mass measurements are very rare, the companion was observed with NPOI over the full 7-year orbit. Our aim was to determine the dynamical mass of a supergiant that, due to the physical separation of more than 10 AU between the components, cannot have undergone mass exchange with the companion. The interferometric observations allow measuring the relative positions of the binary components and their relative brightness. The data collected over the full orbital period allows all seven orbital elements to be determined. In addition to the interferometric observations, we analyzed archival spectra obtained at the Calar Alto, Haute Provence, Cerro Armazones, and La Silla observatories, as well as new spectra obtained at the VLT on Cerro Paranal. In the high-resolution spectra we identified a few lines that can be associated exclusively to one or the other component for the measurement of the radial velocities of both. The combination of astrometry and spectroscopy then yields the stellar masses and the distance to the binary star. The resulting masses for components Aa of 14.0 solar masses and Ab of 7.4 solar masses are low compared to theoretical expectations, with a distance of 294 pc which is smaller than a photometric distance estimate of 387 pc based on the spectral type B0III of the B component. If the latter (because it is also consistent with the distance to the Orion OB1 association) is adopted, the mass of the secondary component Ab of 14 solar masses would agree with classifying a star of type B0.5IV. It is fainter than the primary by about 2.2 magnitudes in the visual. The primary mass is then determined to be 33 solar masses
