Description
We compute for the first time the long-distance penguin contribution to the double radiative $B$-meson decays by applying the perturbative factorization theorem. The numerically dominant penguin amplitude arises from the soft-gluon radiation off the light up-quark loop rather than the counterpart charm-loop effect. Importantly, the long-distance up-quark penguin contribution brings about the...
The Higgs boson (HB) is commonly regarded as the origin of mass within the Standard Model of particle physics (SM). The Higgs produces the electron mass, m_e=0.511 MeV, and the quark current masses, amongst them the light u (up) and d (down) quarks: m_u≈4m_e≈2.2 MeV, m_d≈2m_u. These particles combine to form the hydrogen atom, the most abundant element in the Universe, whose mass is 939 MeV....
