Production of the pentaquark exotic baryon Ξ 5 in KN scattering : KN → K Ξ 5 and KN → K ∗ Ξ 5

چکیده
Abstract We investigate the production of the newly found pentaquark exotic baryon Ξ5 in the KN → KΞ5 and KN → KΞ5 reactions at the tree level. We consider the both positiveand negativeparities of the Ξ5. The reactions are dominated by the sand u-channel processes, and it is observed that the resulting cross sections are very much dependent on the parity of Ξ5 and on the type of form factor. We have seen that the cross sections for the positive-parity Ξ5 are generally about a hundred times larger than those of the negative-parity one. This large difference in the cross sections would be useful for the further study of the pentaquark baryons.

Binary words with a given Diophantine exponent
We prove that every real number ξ > 1 is the Diophantine exponent of some binary word ω. More precisely, we show that Dio(ω) = ξ for ω = 101102103 · · · , where kn = [ξ] for ξ > 2, kn = [ν] with ν = (−ξ + 1 + √ 6ξ − 3ξ2 + 1)/(4− 2ξ) for 1 < ξ < 2, and kn = n for ξ = 1.
متن کاملPower integral bases in a parametric family of totally real cyclic quintics
We consider the totally real cyclic quintic fields Kn = Q(θn), generated by a root θn of the polynomial fn(x) = x 5 + nx − (2n + 6n + 10n + 10)x + (n + 5n + 11n + 15n + 5)x + (n + 4n + 10n + 10)x + 1. Assuming that m = n4 + 5n3 + 15n2 + 25n + 25 is square free, we compute explicitly an integral basis and a set of fundamental units of Kn and prove that Kn has a power integral basis only for n = ...
متن کاملPentaquark Resonances from Collision Times
Having successfully explored the existing relations between the S-matrix and collision times in scattering reactions to study the conventional baryon and meson resonances, the method is now extended to the exotic sector. To be specific, the collision time in various partial waves of KN elastic scattering is evaluated using phase shifts extracted from the KN → KN data as well as from model depen...
متن کاملStatus of Pentaquark Search at Jlab
The possibility of the existence of pentaquarks has been theoretically discussed for many years. However, the subject has been thrust to the forefront during the past two years by the report of the possible observation of a such a state at Spring-8 [1] and ITEP [2]. This was immediately followed up by several positive signals from groups analyzing previously obtained data [3,4,5,6], so that at ...
متن کاملOn Bilinear Littlewood-paley Square Functions
On the real line, let the Fourier transform of kn be k̂n(ξ) = k̂(ξ−n) where k̂(ξ) is a smooth compactly supported function. Consider the bilinear operators Sn(f, g)(x) = ∫ f(x + y)g(x − y)kn(y) dy. If 2 ≤ p, q ≤ ∞, with 1/p + 1/q = 1/2, I prove that ∞ ∑ n=−∞ ‖Sn(f, g)‖2 ≤ C‖f‖p‖g‖q . The constant C depends only upon k.
