WγW\gamma and ZγZ\gamma production and limits on anomalous WWγWW\gamma, ZZγZZ\gamma and ZγγZ\gamma\gamma couplings with D0 detector

The recent D0 results on Wgamma and Zgamma production are presented. First, the cross section and the difference in rapidities between photons and charged leptons for inclusive Wgamma production in egamma and mugamma final states are discussed, then are the cross section and differential cross section as a function of photon transverse momentum for Zgamma process. Finally, I present the limits on anomalous WWgamma, ZZgamma and Zgammagamma couplings.Comment: 18 pages, 16 figures, review articl

|0>|1>+|1>|0>

I give a simple argument that demonstrates that the state |0>|1>+|1>|0>, with |0> denoting a state with 0 particles and |1> a 1-particle state, is entangled in spite of recent claims to the contrary. I also discuss new viewpoints on the old controversy about whether the above state can be said to display single-particle or single-photon nonlocality.Comment: A more serious version, almost 2.36 pages, but still an unnormalized titl

Penentuan Operator Kartu Seluler Terbaik Dengan Metode Ahp (Analytichal Hierarchy Process)

Peranan teknologi telekomunikasi menjadi sanagat penting, terutama dalam pengubah kehidupan masyarakat. Perkembangan teknologi di bidang komunikasi dan informasi kini dapat dinikmati oleh berbagai lapisan masyarakat. Semua lapisan masyarakat dari lapisan elit sampai pembantu rumah tangga dari kota besar ataupun pelosok-pelosok di seluruh Indonesia dapat mengakses sarana telekomunikasi yang ada. Pelayanan jasa telekomunikasi dibawa ke daerah-daerah terisolir, meskipun hasilnya masih belum memuaskan Untuk menentukan alternatif operator kartu seluler yang terbaik yang berdasarkan kriteria tertentu, digunakan metode AHP (Analytical Hierarchy Process). Analytichal Hierarchy Process (AHP) merupakan teknik untuk membantu menyelesaikan masalah. Dalam perkembangannya, AHP tidak hanya digunakan untuk menentukan prioritas pilihan-pilihan dengan banyak kriteria, tetapi penerapannya telah meluas sebagai model alternatif untuk menyelesaikan bermacam- macam masalah. Dari hasil penelitian yang dilakukan pada masyarakat pengguna kartu seluler maupun yang pernah menggunakan kartu seluler Im3, Simpati dan Xl Bebas mulai dari masalah, tujuan, metodologi penelitian dan pengisian kuesioner maka hasil pengambilan keputusan dengan metode AHP diketahui Berdasarkan Alternatif yang terbaik secara keseluruhan adalah Simpati dengan bobot 0.458773073, alternatif terbaik berikutnya adalah XL Bebas dengan bobot 0.346567324, alternatif terbaik berikutnya adalah Im3 dengan bobot 0.194659633

Design and Making the Pulley and Housing Glock Fitness Equipment Lat Pull Down to Be Safe for Users

Pulley is a wheel that rotates on its axis. Pulley used with a chain or rope to lift heavy objects. Pulley can change the direction of the force used to pull or lift objects. Security is very important in penggunanaanya pulley for lifting loads such as fitness equipment. Pulley on fitness equipment designed to avoid the release of the string and the beat of the breakdown of the string. Pulley house is designed to protect the string that can not be separated from the pulley. Housing glock is designed to withstand the buffeting that occurs when a string broke due to the weigh

First Observation of the Decays chi_{cJ} -> pi^0 pi^0 pi^0 pi^0

We present a study of the P-wave spin -triplet charmonium chi_{cJ} decays (J=0,1,2) into pi^0 pi^0 pi^0 pi^0. The analysis is based on 106 million \psiprime decays recorded with the BESIII detector at the BEPCII electron positron collider. The decay into the pi^0 pi^0 pi^0 pi^0 hadronic final state is observed for the first time. We measure the branching fractions B(chi_{c0} -> pi^0 pi^0 pi^0 pi^0)=(3.34 +- 0.06 +- 0.44)*10^{-3}, B(chi_{c1} -> pi^0 pi^0 pi^0 pi^0)=(0.57 +- 0.03 +- 0.08)*10^{-3}, and B(chi_{c2} -> pi^0 pi^0 pi^0 pi^0)=(1.21 +- 0.05 +- 0.16)*10^{-3}, where the uncertainties are statistical and systematical, respectively.Comment: 7 pages, 3 figure

Search for B0→π0π0B^{0}\to \pi^{0}\pi^{0} Decay

We have searched for the charmless hadronic decay of B0 mesons into two neutral pions. Using 9.13fb^-1 taken at the Upsilon(4S) with the CLEO detector, we obtain an improved upper limit for the branching fraction BR(B0-->pi0pi0) < 5.7*10^-6 at the 90% confidence level.Comment: pages postscript, also available through http://w4.lns.cornell.edu/public/CLN

Three-body dispersion-relation N/D equations for the coupled decay channels ppbar (J^{PC}=0^{-+}) --> pi^0 pi^0 pi^0, eta pi^0 pi^0, eta eta pi^0, K Kbar pi^0

During several years the data on different channels ppbar (J^{PC}=0^{-+}) --> 3 mesons presented by Crystal Barrel Collaboration were successfully analyzed by extracting the leading amplitude singularities - pole singularities - with the aim to obtain information about two-meson resonances. But these analyses do not take into account three-body final state interactions (FSI) in an explicitly correct way. This paper is devoted to the consideration of this problem.Comment: 16 pages, no figure
