In the past decade, one of the major challenges of particle physics has been to gain an in-
depth understanding of the role of quark flavor. In this time frame, measurements and the …

One of the most interesting puzzles in particle physics today is that new physics is expected
at the TeV energy scale to solve the hierarchy problem, and stabilises the Higgs mass, but …

A bstract An angular analysis of the B 0→ K* 0 (→ K+ π−) μ+ μ− decay is presented. The
dataset corresponds to an integrated luminosity of 3.0 fb− 1 of pp collision data collected at …

In a sample of 471× 10 6 BB¯ events collected with the BABAR detector at the PEP-II e+ e-
collider we study the rare decays B→ K (*) ℓ+ ℓ-, where ℓ+ ℓ-is either e+ e-or μ+ μ-. We …

The series Lecture Notes in Physics (LNP), founded in 1969, reports new developments in
physics research and teaching-quickly and informally, but with a high quality and the explicit …

We calculate the long-distance effect generated by the four-quark operators with c-quarks in
the B→ K (*) ℓ+ ℓ− decays. At the lepton-pair invariant masses far below the\(\bar {c} c\) …

Angular distributions of the decay B 0→ K⁎ 0 μ+ μ− are studied using a sample of proton–
proton collisions at s= 8 TeV collected with the CMS detector at the LHC, corresponding to …

The rare decay B-> K*(-> K pi) mu+ mu-is regarded as one of the crucial channels for B
physics as the polarization of the K* allows a precise angular reconstruction resulting in …

The angular distributions and the differential branching fraction of the decay B 0→ K⁎(892)
0 μ+ μ− are studied using data corresponding to an integrated luminosity of 20.5 fb− 1 …

We model-independently analyze the angular distributions of bar B→ K bar l ldecays, l= e, μ,
for low dilepton mass using QCD factorization. Besides the decay rate, we study the forward …
