Spectral Functions for Heavy-Light Currents and Form Factor Relations in Hqet

, 1992
We derive relations among form factors describing the current-induced transitions: (vacuum) $\rightarrow B,B^{*}, B \pi, B^{*} \pi, B \rho$ and $B^{*} \rho$ using heavy quark symmetry.

Using an amplitude analysis to measure the photon polarisation in $$B \rightarrow K\pi \pi \gamma $$ B→Kππγ decays

European Physical Journal C: Particles and Fields, 2019
A method is proposed to measure the photon polarisation parameter $$\lambda _{\gamma }$$ λγ in $${{b}} \!\rightarrow {s} {\gamma } $$ b→sγ transitions using an amplitude analysis of $$B\!\rightarrow K\pi \pi {\gamma } $$ B→Kππγ decays.

The geometry of $\Pi$-invertible sheaves

, 2014
Using the fact that $\Pi$-invertible sheaves can be interpreted as locally free sheaves of modules for the super skew field $\mathbb{D}$, we give a new construction of the $\Pi$-projective superspace $\mathbb{P}^n_{\Pi, B}$ over affine $k$ superschemes ...

Kaon versus Antikaon Production at SIS Energies [PDF]

, 1996
We analyse the production and propagation of kaons and antikaons in Ni + Ni reactions from 0.8--1.85 GeV/u within a coupled channel transport approach including the channels $BB \to K^+YN, \pi B\to K^+Y, BB \to NN K \bar{K}, \pi B\to N K\bar{K}, K^+B\to ...

Observation of the Cabibbo-suppressed decay Xi_c+ -> p K- pi+

, 1999
We report the first observation of the Cabibbo-suppressed charm baryon decay Xi_c+ -> p K- pi+. We observe 150 +- 22 events for the signal. The data were accumulated using the SELEX spectrometer during the 1996-1997 fixed target run at Fermilab, chiefly ...

Why and When Are Evidence‐Based Interventions Adopted in Paediatric Supportive Care? A Qualitative Exploration of the Determinants of Photobiomodulation Implementation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Oral mucositis is a common and debilitating side effect of childhood cancer and stem cell transplant treatments. It affects the quality of life of children and young people (CYP) and places a strain on services. Photobiomodulation is recommended for oral mucositis prevention in international guidance but is poorly implemented in UK ...

Are the anti-charmed and bottomed pentaquarks molecular heptaquarks?

, 2004
I study the charmed $uudd\bar c$ resonance D*p (3100) very recently discovered by the H1 collaboration at Hera. An anticharmed resonance was already predicted, in a recent publication mostly dedicated to the S=1 resonance Theta+(1540).

Adherence to Protocol Recommendations for Children With Wilms Tumour in Two Consecutive Studies in the United Kingdom and Ireland—Does Variation Matter?

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background and Aims Wilms tumour (WT) has excellent event‐free and overall survival (OS). However, small differences exist between countries participating in the same international study. This led us to examine variation in adherence to protocol recommendations as a potential contributing factor.

The S-wave resonance contributions in the $$B^{0}_{s}$$ B s 0 decays into $$\psi (2S,3S)$$ ψ ( 2 S , 3 S ) plus pion pair

European Physical Journal C: Particles and Fields, 2017
The three-body decays $$B^0_s \rightarrow \psi (2S,3S) \pi ^+ \pi ^-$$ B s 0 → ψ ( 2 S , 3 S ) π + π - are studied based on the perturbative QCD approach.

Pediatric Oncology Nursing Competencies in Latin America and the Caribbean: A Scoping Review to Inform Practice, Education, and Research

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Nurses are central to cancer care for children and adolescents, yet no comprehensive synthesis has defined essential core competencies for pediatric oncology nursing (PON) practice internationally, particularly in Latin America and the Caribbean (LAC).
