Precision physics at the muon collider: m W and CKM matrix elements

Journal of High Energy Physics
We examine the potential for a 10 TeV lepton collider to carry out precision measurements of the W boson mass and W boson couplings strength, i.e. the CKM matrix elements.

Ion Activation Methods for Top‐Down Proteomics

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)

Charm Phenomenology for CKM Parameters

, 2003
We review several key aspects of charm phenomenology which are important for the general program of determination of matrix elements of the Cabbibo-Kobayashi-Maskava (CKM) matrix. We argue that charm physics plays an important role in reducing uncertainties in non-perturbative QCD parameters whose values are required for understanding of underlying ...

Evolution of sea fog based on meteorological and oceanographic observations during FATIMA Yellow Sea campaign

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study presents a conceptual framework linking sea‐water temperature Tw gradients to the formation and persistence of sea fog in the southeastern Yellow Sea. Over cold waters maintained by tidal mixing, downward latent heat flux enhances lower‐level stability and sustains persistent sea fog, whereas over warmer waters, upward fluxes and thermal ...

Measurements of the CKM angle γ at LHCb

, 2020
The angle γ is the only complex phase of the Cabibbo-KobayashiMaskawa (CKM) matrix that can be measured at tree level. It therefore establishes a benchmark of the Standard Model (SM) against which loop-level measurements of the CKM parameters can be ...

Constraining the CKM parameters usingCPviolation in semileptonicBdecays [PDF]

Physical Review D, 1999
We discuss the usefulness of the CP violating semi-leptonic asymmetry a_{SL} not only as a signal of new physics, but also as a tool in constraining the CKM parameters. We show that this technique could yield useful results in the first years of running at the B factories.

Spontaneous CP violation in supersymmetric QCD

Journal of High Energy Physics
We investigate a composite model of spontaneous CP violation based on a new supersymmetric QCD as a solution to the strong CP problem. The scalar components of the meson chiral superfields obtain complex vacuum expectation values to break CP symmetry ...

Blubber Thickening Driven by UCP1 Inactivation: Insights from a Cetacean‐Like Transgenic Mouse Model

Integrative Zoology, EarlyView.
UCP1 inactivation of cetaceans in mice drives BAT whitening and iWAT hyperplasia, promoting fat accumulation for aquatic adaptation. Abstract Cetaceans possess thick blubber, a specialized adipose tissue essential for thermal insulation, a streamlined body form, energy storage, and buoyancy. However, the mechanisms that underpin this adaptation are not

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.
