Flavor constraints from pp → Vh and pp → WV at the LHC

Journal of High Energy Physics
We investigate the potential of associated Higgs pp → Vh and diboson production pp → WV channels at the LHC (with V = W, Z) to constrain flavor-physics operators.

New sum rules for the B c → J/ψ form factors

Journal of High Energy Physics, 2023
We derive new sum rules for the form factors of the B c → J / ψ ℓ ν ¯ ℓ $$ {B}_c\to J/\psi \ell {\overline{\nu}}_{\ell } $$ semileptonic transitions, employing the vacuum-to-B c correlation function of the J/ψ-interpolating and b → c weak currents.

CP Violation and Flavour Mixing in the Standard Model -- 1996 Update [PDF]

, 1996
We review and update the constraints on the parameters of the quark flavour mixing matrix $V_{CKM}$ in the standard model and estimate the resulting CP asymmetries in $B$ decays, taking into account recent experimental and theoretical developments.

Chlorella vulgaris biorefineries: sustainable biofuels and high‐value carbon capture

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Global reliance on fossil fuels has created urgent economic and environmental challenges, yet large‐scale use of algal biomass remains limited by production costs. Industrial scaling is constrained by inefficient harvesting and the technical challenges of processing recalcitrant cell walls.

Measurement of the branching ratio of the decay and extraction of the CKM parameter [PDF]

Physics Letters B, 2004
We present a new measurement of the branching ratio R of the decay KL→πeν, denoted as Ke3, relative to all charged KL decays with two tracks, based on data taken with the NA48 detector at the CERN SPS. We measure R = 0.4978 ±0.0035. From this we derive the Ke3 branching fraction and the weak coupling parameter |Vus | in the CKM matrix. We obtain |Vus |

Minimally modified Fritzsch texture for quark masses and CKM mixing

Journal of High Energy Physics, 2023
The Standard Model does not constrain the form of the Yukawa matrices and thus the origin of fermion mass hierarchies and mixing pattern remains puzzling.

The CKM Matrix from Lattice QCD

, 2009
Lattice QCD plays an essential role in testing and determining the parameters of the CKM theory of flavor mixing and CP violation. Very high precisions are required for lattice calculations analysing CKM data; I discuss the prospects for achieving them ...

Heterozygous Med13l mice recapitulate a developmental growth delay and craniofacial anomalies seen in MED13L syndrome

Developmental Dynamics, EarlyView.
Abstract Background Gene transcription is crucial for embryo and postnatal development and is regulated by the Mediator complex. Mediator is comprised of four submodules, including the kinase submodule (CKM). The CKM consists of MED13, MED12, CDK8, and CCNC.

Inequalities for Standard Model Yukawa couplings

Journal of High Energy Physics
We show that the Standard Model Yukawa matrices satisfy a set of simple yet nontrivial inequalities. The relations we derive are independent of the basis used to define the fermion fields, and, amongst other things, place strong constraints on the ...

Toward a complete description of b → uℓ − ν ¯ $$ \overline{\nu} $$ within the Weak Effective Theory decays

Journal of High Energy Physics, 2023
We fit the available data on exclusive semileptonic b → uℓ − ν ¯ $$ \overline{\nu} $$ decays within the Standard Model and in the Weak Effective Theory. Assuming Standard Model dynamics, we find V ub = 3.59 − 0.12 + 0.13 × 10 − 3 $$ \left|{V}_{ub}\right|=
