Academic Provenance: Original Master's thesis authored by Loran Jacobs at the Moscow Engineering Physics Institute (MEPhI), Department of Theoretical Nuclear Physics, carried out jointly with the Institute for Theoretical and Experimental Physics (ITEP), Moscow, 2005. Scientific supervisor: M. I. Vysotsky, Corresponding Member of the Academy of Sciences.

Core Scientific Value: A theoretical study of CP-symmetry violation in the decays of neutral and charged B mesons into a pair of pions and of the extraction of the unitarity angle α. An isospin analysis separates the tree and penguin contributions. Sixteen values of the angle α are found, classified into four families, and the theoretical errors are derived from the experimental errors of the B-decay data. The results agree with the predictions of the Standard Model.

Key Research Areas:

• The Cabibbo–Kobayashi–Maskawa (CKM) matrix and CP-violation in decays of K and B mesons.

• Isospin analysis of B → ππ decays and the role of penguin amplitudes.

• Extraction of the angle α from experimental data and its comparison with the Standard Model.
