abstract

The rare decay $\bar B\to X_s\gamma$ is an important probe of physics beyond the standard model. The largest uncertainty on the total rate and the CP asymmetry arises from resolved photon contributions. These appear first at order $1/m_b$ and are related to operators other than $Q_{7\gamma}$ in the effective weak Hamiltonian. One of the three leading contributions, $Q^q_1-Q_{7\gamma}$, is described by a non-local function whose moments are related to HQET parameters. We use recent progress in our knowledge of these parameters to reevaluate the resolved photon contribution to $\bar B\to X_s\gamma$ total rate and CP asymmetry.

  1. Photon-Tagged Energy Flow in Inclusive Endpoint $B$ Decays

    hep-ph 2026-07 accept novelty 7.0 of 10

    A new photon-tagged angular energy correlator in inclusive B→X_sγ factorizes at leading power into the standard shape function and a newly computed measured jet function, enabling angular tests of endpoint factorization.

  2. Renormalisation group evolution of the shape function $g_{17}$ in $\bar{B}\to X_s \gamma$ and $\bar{B} \to X_s \ell^+\ell^-$ at subleading power

    hep-ph 2024-11 conditional novelty 7.0 of 10

    The authors derive and solve the renormalization-group equation for the subleading shape function g17(ω,ω1;μ) in inclusive B decays, and simplify the RG evolution of a related exclusive soft function.

  3. Light Scalars in the Extended Georgi-Machacek Model

    hep-ph 2025-06 conditional novelty 6.0 of 10

    A global fit of the Georgi-Machacek and extended Georgi-Machacek models finds that the 95 GeV diphoton and bottom-quark excesses are compatible with the 125 GeV Higgs data, while the ditau excess is not, and it sets u...
