Form factors in from QCD light-cone sum rules

Christian Hambrock, Alexander Khodjamirian

The form factors of the semileptonic decay are calculated from QCD light-cone sum rules with the distribution amplitudes of dipion states. This method is valid i…

Hadronic effects and observables in decay at large recoil

Christian Hambrock, Alexander Khodjamirian, Aleksey Rusov

We calculate the amplitude of the rare flavour-changing neutral-current decay at large recoil of the pion. The nonlocal contributions in which the weak effecti…

B -> K^* Form Factors from Flavor Data to QCD and Back

Christian Hambrock, Gudrun Hiller, Stefan Schacht +1

Sufficient control of transition form factors is a vital ingredient for the precision flavor programs including the nearer term searches at the Large Hadron Collider (LHC) and the…

Exotic Heavy Quark Spectroscopy - Theory Interpretation vs Data

Christian Hambrock

An overview over recent spectroscopy results in comparison with data is given. We focus on the exotica Z_b(10610), Z_b(10650) and Y_b(10890) in the bottom sector and discuss a poss…

Hadroproduction of above Thresholds and Implications for

Ahmed Ali, Christian Hambrock, Wei Wang

Based on the non-relativistic QCD factorization scheme, we study the hadroproduction of the bottomonium states and . We argue to search for them in the final states…

Light-Cone Distribution Amplitudes of the Ground State Bottom Baryons in HQET

A. Ali, C. Hambrock, A. Ya. Parkhomenko +1

We provide the definition of the complete set of light-cone distribution amplitudes (LCDAs) for the ground state heavy bottom baryons with the spin-parities J^P = 1/2^+ and J^P = 3…

Extracting Form Factors from Data

Christian Hambrock, Gudrun Hiller

We extract ratios of form factors at low hadronic recoil from recent data on decays in a model-independent way. The presented method will improve in…

Tetraquark Interpretation of the Charged Bottomonium-like states Z_b^+-(10610) and Z_b^+-(10650) and Implications

Ahmed Ali, Christian Hambrock, Wei Wang

We present a tetraquark interpretation of the charged bottomonium-like states Z+-_b(10610) and Z+-_b(10650), observed by the Belle collaboration in the pi+- Upsilon(nS) (n=1,2,3) a…

Tetraquark-based analysis and predictions of the cross sections and distributions for the processes e^+ e^- --> Upsilon(1S) (pi^+ pi^-, K^+ K^-, eta pi^0) near Upsilon(5S)

Ahmed Ali, Christian Hambrock, Satoshi Mishima

We calculate the cross sections and final state distributions for the processes e^+ e^- --> Upsilon(1S) (pi^+ pi^-, K^+ K^-, eta pi^0) near the Upsilon(5S) resonance based on the t…

A case for hidden tetraquarks based on cross section between and 11.20 GeV

Ahmed Ali, Christian Hambrock, Ishtiaq Ahmed +1

We study the spectroscopy and dominant decays of the bottomonium-like tetraquarks (bound diquarks-antidiquarks), focusing on the lowest lying P-wave states $…
