Add   Nucleon structure in a light-front quark model consistent with quark counting rules and data
Authors: Gutsche, Thomas | Schmidt, Ivan A. | Vega, Alfredo | Lyubovitskij, Valery E.
Source: Physical Review D. 2015. Vol. 91, № 5. P. 054028-1-054028-10
Type: статьи в журналах
Date: 2015
Description: Using global fits of valence u and d quark parton distributions and data on quark and nucleon form factors in the Euclidean region, we derive a light-front quark model for the nucleon structure consis ... More
Add   Nucleon structure including high Fock states in AdS/QCD models
Authors: Vega, Alfredo | Gutsche, Thomas | Lyubovitskij, Valery E. | Schmidt, Ivan A
Source: Few-body systems. 2015. Vol. 56, № 6. P. 633-637
Type: статьи в журналах
Date: 2015
Description: We discuss a holographic soft-wall model that consider several Fock states in nucleon description. In our approach nucleon structure is a superposition of a three-valence quark state with high Fock st ... More
Add   On the meson mass spectrum in the covariant confined quark model
Authors: Ganbold, Gurjav | Ivanov, Mikhail A. | Lyubovitskij, Valery E. | Gutsche, Thomas
Source: Journal of physics G: Nuclear and particle physics. 2015. Vol. 42, № 7. P. 075002 (1-8)
Type: статьи в журналах
Date: 2015
Description: We provide a new insight into the problem of generating the hadron mass spectrum in the framework of the covariant confined quark model. One of the underlying principles of this model is the composite ... More
Add   Pion light-front wave function, parton distribution and the electromagnetic form factor
Authors: Gutsche, Thomas | Schmidt, Ivan A. | Vega, Alfredo | Lyubovitskij, Valery E.
Source: Journal of physics G: Nuclear and particle physics. 2015. Vol. 42, № 9. P. 095005 (1-8)
Type: статьи в журналах
Date: 2015
Description: We derive the lowest-order qq valence light-front wave function for the pion with Lz = 0 and |Lz| = 1, which reproduces its valence parton distribution and the electromagnetic form factor consistent w ... More
Add   Role of multichannel ππ scattering in decays of bottomia
Authors: Surovtsev, Yurii S. | Gutsche, Thomas | Kamiński, Robert | Lyubovitskij, Valery E. | Nagy, Miroslav | Bydžovský, Petr
Source: Physical Review D. 2015. Vol. 91, № 3. P. 037901-1-037901-4
Type: статьи в журналах
Date: 2015
Description: The effect of isoscalar S-wave multichannel ππ→ππ, KK¯¯,ηη scattering is considered in the analysis of decay data of the Υ-mesons. We show that when allowing for the final state interaction contributi ... More
Add   Semileptonic decay Ʌb→Ʌc+τ͞͞ +͞͞ν τ in the covariant confined quark model
Authors: Gutsche, Thomas | Körner, Jürgen G. | Lyubovitskij, Valery E. | Santorelli, Pietro | Habyl, Nurgul | Ivanov, Mikhail A.
Source: Physical Review D. 2015. Vol. 91, № 7. P. 074001-1-074001-20
Type: статьи в журналах
Date: 2015
Description: Recently there has been much interest in the tauonic semileptonic meson decays B→D+τ+ντ and B→D∗+τ+ντ, where one has found larger rates than what is predicted by the Standard Model. We analyze the cor ... More
Add   Unified description of BABAR and Belle data on the bottomonia decays Υ(mS)→Υ(nS)π+π-

Source: Physical Review D. 2015. Vol. 92, № 3. P. 036002-1-036002-8
Type: статьи в журналах
Date: 2015
Description: We present a unified analysis of the decays of bottomonia Υ(mS)→Υ(nS)ππ (m>n, m=2,3,4,5, n=1,2,3), charmonia J/ψ→ϕ(ππ,KK¯), ψ(2S)→J/ψππ, and the isoscalar S-wave processes ππ→ππ,KK¯,ηη. In this analys ... More
