Enhanced $B_q\to \ell {\ell }^{\prime }$ and $B\to (K,\pi )\ell {\ell }^{\prime }$ in light of $(g-2{)}_{\mu }$

Physical Review, 2023
We study lepton flavor violating (LFV) B decays in a general two Higgs doublet model with sub-TeV exotic scalars. Two different parameter spaces are explored: one dominated by extra top Yukawa coupling ρtt, the other by LFV couplings relevant for the muon g−2 anomaly. In the first case, flavor constraints such as ℓ→ℓ′γ, h→ℓℓ′ imply LFV B decays are far

Communication and Language Profiles of Children Treated for Posterior Fossa Brain Tumors

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cognitive and language deficits are frequently reported sequelae of posterior fossa brain tumors (PFBT). Typically, delayed onset impedes prompt assessment and early intervention. This has devastating implications for quality of life.

Sobolev Estimates for the $\overline{\partial }$ and the $\overline{\partial }$-Neumann Operator on Pseudoconvex Manifolds

Mathematics, 2023
Let D be a relatively compact domain in an n-dimensional Kähler manifold with a C2 smooth boundary that satisfies some “Hartogs-pseudoconvexity” condition.

${\Lambda }_b\to {\Lambda }^{*}\left(1520\right){\ell }^{+}{\ell }^{-}$ form factors from lattice QCD

Physical Review, 2021
We present the first lattice QCD determination of the Λb→Λ*(1520) vector, axial vector, and tensor form factors that are relevant for the rare decays Λb→Λ*(1520)ℓ+ℓ−. The lattice calculation is performed in the Λ*(1520) rest frame with nonzero Λb momenta, and is limited to the high-q2 region. An interpolating field with covariant derivatives is used to

The HIT Network for Children and Adolescents With CNS Tumors Facilitates Improvements of Diagnostic Assessments, Multimodal Treatments, Individual Counseling, and Research in Germany, Austria, and Switzerland

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background The HIT network was established in 2000 to create a population‐based structure aiming to improve survival rates and reduce late effects for children with central nervous system (CNS) tumors by conducting comprehensive clinical trials.

Resonant contributions to three-body $B_{\left(s\right)}\to [D^{(*)},{\overline{D}}^{(*)}]K^{+}{K}^{-}$ decays in the perturbative QCD approach

Physical Review, 2020
In this work, we study the S, P, and D wave resonance contributions to three-body decays B(s)→[D(*),D¯(*)]K+K− by employing the perturbative QCD (PQCD) approach, where the kaon-kaon invariant mass spectra are dominated by the f0(980), f0(1370), ϕ(1020), ϕ(1680), f2(1270), f2′(1525), f2(1750), and f2(1950) resonances.

Stressful Events Reported by Childhood Cancer Survivors and Community Controls From the St. Jude Lifetime (SJLIFE) Cohort: A Mixed Method Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Characterizing stressful events reported by childhood cancer survivors experienced throughout the lifespan may help improve trauma‐informed care relevant to the survivor experience. Methods Participants included 2552 survivors (54% female; 34 years of age) and 469 community controls (62% female; 33 years of age) from the St.

Hořava–Lifshitz $F\left(\overline{R}\right)$ Theories and the Swampland

Universe, 2023
The compatibility between the de Sitter Swampland conjecture and Hořava–Lifshitz F(R¯) theories with a flat FLRW metric is studied. We first study the standard f(R) theories and show that the only way in which the dS conjecture can be made independent of

Two-gap superconductivity in Mo$_{8}$Ga$_{41}$ and its evolution upon the V substitution

, 2017
Zero-field and transverse-field muon spin rotation/relaxation ($\mu$SR) experiments were undertaken in order to elucidate microscopic properties of a strongly-coupled superconductor Mo$_{8}$Ga$_{41}$ with $T_{\text{c}}=9.8$ K.
