Decay matrix of B-\bar{B} mixing: Mixing of dimension-seven operators into dimension-six operators under renormalization
Artyom Hovhannisyan, Ulrich Nierste
The precise measurement of the width difference ΔΓ_s among the mass eigenstates of the B_s-\bar{B}_s system requires the calculation of the corresponding decay matrix to order α_s/…
Addendum: Towards next-to-next-to-leading-log accuracy for the width difference in the system: fermionic contributions to order and
Artyom Hovhannisyan, Ulrich Nierste
We calculate the three-loop master integrals of Ref. [1] [arXiv:1709.02160] in analytic form. This allows us to present the fermionic contributions to the Wilson coefficient…
Penguin contribution to width difference and CP asymmetry in - mixing at order
Hrachia M. Asatrian, Hrachya H. Asatryan, Artyom Hovhannisyan +3
We present new contributions to the decay matrix element of the - mixing complex, where or . Our new results constitute the order cor…
Towards next-to-next-to-leading-log accuracy for the width difference in the system: fermionic contributions to order and
H. M. Asatrian, Artyom Hovhannisyan, Ulrich Nierste +1
We calculate a class of three-loop Feynman diagrams which contribute to the next-to-next-to-leading logarithmic approximation for the width difference in the $B_s-\bar{B}_…
Phase space analysis for three and four massive particles in final states
H. M. Asatrian, A. Hovhannisyan, A. Yeghiazaryan
We propose formulae for computing the phase space integrals of and processes with massive particles in final states. As an application of these formulae we study…
Forward-backward asymmetry of Drell-Yan lepton pairs in pp collisions at sqrt(s) = 7 TeV
CMS Collaboration
A measurement of the forward-backward asymmetry (A[FB]) of Drell-Yan lepton pairs in pp collisions at sqrt(s) = 7 TeV is presented. The data sample, collected with the CMS detector…
