Observation of pi(+)pi(-)pi(+)pi(-) photoproduction in ultraperipheral heavy-ion collisions at root s(NN)=200 GeV at the STAR detector

We present a measurement of pi(+)pi(-)pi(+)pi(-) photonuclear production in ultraperipheral Au-Au collisions at root s(NN) = 200 GeV from the STAR experiment. The pi(+)pi(-)pi(+)pi

Measurement of the wrong-sign decay D-0 -> K+pi(-)pi(+)pi(-)

A measurement of the rate for the "wrong-sign" decay D-0 -> K+pi(-)pi(+)pi(-) relative to that for the "right-sign" decay D-0 -> K-pi(+)pi(+)pi(-) is presented this ratio by the world average valu...

Unitary Multi-channel pi pi Scattering Apmlitudes of f(2) and rho(3) Mesons

In a unitary multi-channel approach, precise determination of pi pi scattering amplitudes for D and F waves has been presented. These scattering amplitudes are in the I(G)J(PC) = 0(+)2(++) sector of the processes of pi ...

Upgraded DIRAC spectrometer at CERN PS for the investigation of pi pi and pi K atoms

simultaneously A(2 pi) and A(pi K) atoms, namely the bound states of two pi mesons, and of pi-acquisition system can handle a very large amount of data to identify pi, K, p, e and mu, allowing the selecti...

Observation of pi K--(+) and pi K-+(-) Atoms

The observation of hydrogenlike pi K atoms, consisting of pi K--(+) or pi K) of pi K atoms in the same targets yields characteristic pi K pairs, called "atomic. The upgraded DIRAC experiment observed 349 +...

'Pi' in the sky

We argue for a procedural semantics for mathematical constants, using 'Pi' as a hard test case. The semantics of 'Pi' consists in 'Pi' expressing as its sense a procedure producing the number Pi. What is semantical...
