We briefly review the status of various conventional quark-antiquark mesons below 2 GeV and outline some open questions: strangeantistrange orbitally excited vector meson, nonet axial-tensor (chiral partners well known tensor mesons), isoscalar mixing angle in pseudotensor sector, which can eventually represent a novel manifestation chiral anomaly.

Perubahan wilayah dari perdesaan menjadi perkotaan menyebabkan terjadinya perubahan iklim. Iklim yang berubah tersebut terjadinyan peningkatan hujan ekstrim. catatan data ektrim, analisis frekuensi tidak valid karena kondisi stasioner. Oleh hal tersebut, maka dilakukan adaptasi pembuatan lengkung IDF dan rencana menggunakan non Contoh kasus digunakan adalah di Kota Bekasi Cikarang, dimana kedua...

The measurement of multiple strange particles provides information on the hadronization features of strongly interacting matter produced in heavy ion collisions. If we assume that a deconfinement phase transition occurs in a heavy ion collision, we have to look for qualitative changes (onset phenomena) when varying external parameters like system size and energy density. Therefore we study the ...

We introduce the Statistical Hadronization with Resonances (SHARE) suite of programs and perform a study of particle multiplicities as well as bulk thermodynamic quantities for the RHIC Au–Au reactions at √ sNN = 130 GeV. We also show that the statistical hadronization model, with parameters fitted to match pion, proton and hyperon ratios, in turn correctly and consistently reproduces rapidity ...

Allowing for variations in behaviour across respondents is one of the most fundamental principles in discrete choice modelling, given that the assumption of a purely homogeneous population cannot in general (or ever) be seen to be valid. Two approaches have classically been used to address this problem; the use of deterministic segmentations of the population, and the use of a random continuous...

The bottom quark pole mass M b is determined using a sum rule which relates the masses and the electronic decay widths of the Υ mesons to large n moments of the vacuum polarization function calculated from nonrelativistic quantum chromodynamics. The complete set of next-to-next-to-leading order (i.e. O(α 2 s , α s v, v 2) where v is the bottom quark c.m. velocity) corrections is calculated and ...

If supersymmetry will be realized in nature precise mass measurements of the particle spectrum will be very important in order to determine the underlying theory. The potential of the proposed Tesla Linear Collider 1 will be studied within a R-parity conserving mSUGRA scenario with parameters m0 = 100 GeV, m1/2 = 200 GeV, A0 = 0 GeV, tanβ = 3 and sgn(μ) > 0. In general SUSY signatures are fairl...
