The DIRAC experiment at CERN has achieved a sizeable production of $\pi^+\pi^-$ atoms and significantly improved the precision on its lifetime determination. From sample 21227 atomic pairs, 4% measurement S-wave $\pi\pi$ scattering length difference $|a_0-a_2| = (.0.2533^{+0.0080}_{-0.0078}|_\mathrm{stat}.{}^{+0.0078}_{-0.0073}|_\mathrm{syst})M_{\pi^+}^{-1}$ been attained, providing an important test Chiral Perturbation Theory.
The electromagnetic form factors of spin-1/2 particles are known, but due to historical reasons only half them found in many textbooks. Given the importance general result, its model independence, connection discrete symmetries and their violations we made an effort derive present result based on knowledge Dirac equation. We discuss phenomenology connected directly with factors, spin precession external fields including time reversal violating terms. apply formalism spin-flip synchrotron...
Charge Parity asymmetry in charmless B meson decays is a key issue to be understood. Many theoretical calculations have been performed using short distance factorization approaches which, general, do not take into account the CPT invariance constraint. For each channel with CP violation there an equal amount of another or other channels, opposite sign. This happens if these channels are coupled through final state interactions (FSI). In specific process $B\to PV$, involving one pseudo-scalar...
Abstract Muon tomography is a technique based on the observation of absorption muons in matter, as ordinary radiography does using X-rays. The interaction cosmic rays with atmosphere produce Extensive Air Showers, which provide an abundant source muons. These particles can be used for multiple applications muon tomography, particular, to study internal structure different volcanoes edifices. It necessary any experiment particle detector that has capability sensitive interactions. Here we...
Muon radiography is based on the observation of absorption muons in matter, as ordinary does by using X-rays. The interaction cosmic rays with atmosphere produce Extensive Air Showers (EAS), which provide abundant source muons. These particles can be used for various applications muon radiography, particular to study internal structure different volcanoes edifice. We will focus Galeras volcano located 9 km from Pasto city (Colombia). In this work we present first lateral distribution at...
Northwest Arkansas has well-developed karst systems, with numerous sinking streams and springs.Karst conduits make it easy for contaminants to enter groundwater degrading the water quality destroying fragile ecosystems.With increase of urbanization, potential threats in form fecal contamination may prove be more a problem.The purpose this research is compare difference between microbial communities within two different settings, aquifer surface stream.The Blowing Spring Cave Little Sugar...
