Prediction of possible exotic states in the system *

Abstract

We investigate the ηKK * three body system in order to look for possible I G (J P C ) = 0 + (1 −+ ) exotic states within the framework of the fixed center approximation to the Faddeev equation. The study is made assuming scattering of a η on a clusterized systemKK * , which has known to generate the f1(1285) or aK on a clusterized system ηK * , which is shown to generate the K1(1270). In the case of the η-(KK * ) f 1 (1285) scattering, we find evidence of a bound state I G (J P C ) = 0 + (1 −+ ) below the ηf1(1285) threshold with mass around 1700 MeV and width about 180 MeV. On the other hand, considering theK-(ηK * ) K 1 (1270) scattering, we obtain a bound state I(J P ) = 0(1 − ) just below thē KK1(1270) threshold with mass around 1680 MeV and width about 160 MeV.PACS numbers:

Anisotropic heating and magnetic field generation due to Raman scattering in laser-plasma interactions

“…Understanding the interaction between electromagnetic waves and plasmas is of fundamental importance with implications in inertial confinement fusion, plasmabased accelerators, and laboratory astrophysics. The ability to use the interaction of intense lasers with plasmas to reproduce astrophysical scenarios in the laboratory is a powerful tool to explore astrophysical phenomena [1,2], specifically in connection with laser-plasma produced magnetic fields. Several mechanisms for magnetic field generation, such as the Biermann battery and the inverse Faraday effect, have been discussed over the years [3][4][5][6][7][8][9][10][11].…”

Hadron spectroscopy at STCF

“…J/ψ → V η 1 , where V stands for ω or φ) can play an important role in unraveling the quark content of the η 1 (1855). Searching for the decay mode of K 1 K and three body decays will be crucial to discriminate molecule hypothesis for the η 1 (1855) [63,64]. In addition, more precise study on the isoscalar 1 −+ η 1 (1855), combined with previous and also future measurements of the isovector π 1 states, will provide critical clue of searching for other partners of hybrid supermulitplets.…”

Towards the establishment of the light $J^{P(C)}=1^{-(+)}$ hybrid nonet

“…In Ref. [27], it is investigated that an isoscalar with I G (J P C ) = 0 + (1 −+ ) may be formed as a bound state of η KK * . However, the mass is much lower than η 1 (1855).…”
