scalar meson meaning in Hindi

Examples

1. The heavier scalar mesons containing charm and / or bottom quarks all occur well over 2 GeV / c 2.
2. The " Particle Data Group " provides current information on the experimental status of various particles, including the scalar mesons.
3. Many attempts have been made to determine the quark content of the lighter scalar mesons; however, no consensus has yet been reached.
4. The first known scalar mesons have been observed since the late 1950s, with observations of numerous light states and heavier states proliferating since the 1980s.
5. In this realm, the radiative processes tend to stand out, with heavy tensor and scalar mesons decaying dominantly into vector mesons by photon emission.
6. The scalar mesons in the mass range below 1 GeV / c 2 are much more controversial, and may be interpreted in a number of different ways.
7. The tetraquark interpretation works well with the MIT Bag Model of QCD, where the scalar tetraquarks are actually predicted to have lower mass than the conventional scalar mesons.
8. Ever since Jaffe first suggested the existence of tetraquark multiplets in 1977, the lightest scalar mesons have been interpreted by some theorists to be possible tetraquark or meson-meson molecule states.
9. This characteristic of the vector mesons is not at all evident in the pseudoscalar meson or scalar meson multiplets, and may be only slightly realized among the tensor meson and pseudovector meson multiplets.
10. With the re-introduction of the sigma meson as an acceptable candidate for a light scalar meson in 1996 by Tornqvist and Roos, in-depth studies into the lightest scalar mesons were conducted with renewed interest.
