Testing CPT with B mesons

AIP Conference Proceedings, 1998
Apparent violations of CPT and Lorentz symmetry might arise in nature as a result of spontaneous symmetry breaking in a theory beyond the standard model. This talk summarizes a few relevant theoretical and experimental issues, with some emphasis on implications for CPT tests with neutral-B mesons.

Analysis of anxiety levels and perceived satisfaction after a first encounter with human body prosection among nursing undergraduates based on their self‐perceived presession nervousness: An observational study

Anatomical Sciences Education, EarlyView.
Abstract Human body prosection practices are a crucial educational tool for learning anatomy. However, the first exposure to donors' material can cause anxiety, which may affect students' learning experiences and emotional adjustment. This observational study aimed to analyze anxiety levels (state and trait) before and after a prosection session in ...

Exploring electromagnetic characteristics of the vector and axial-vector $$B_c$$ B c mesons

European Physical Journal C: Particles and Fields
The magnetic moments of the $$B_c$$ B c mesons provide significant insights into their inner structure and geometric shape. Furthermore, a comprehensive understanding of the electromagnetic characteristics of $$B_c$$ B c mesons is essential for advancing

Statistical production of Bc mesons in heavy-ion collisions at the LHC energy

Physics Letters B
The recombination production of Bc mesons in heavy-ion collisions at the LHC energy is facilitated by the abundant and highly thermalized charm (c) quarks transported in the deconfined medium created. We study the production of Bc mesons via c and bottom

CP Violation Studies in B Mesons

EPJ Web of Conferences, 2013
The four general purpose detectors on the Tevatron (CDF, D0) and LHC (Atlas, CMS) hadron colliders continue to make important measurements in the field of CP violation (CPV) in B hadron physics. The CDF collaboration presents new results in direct CPV of

Study of the nonleptonic charmless $$B \rightarrow SS$$ B → S S decays with the QCD factorization approach

European Physical Journal C: Particles and Fields, 2023
Inspired by the brilliant prospects of the ongoing B meson experiments, the hadronic charmless B $${\rightarrow }$$ → SS decays are studied by considering the next-to-leading (NLO) contributions with the QCD factorization approach, where S denotes the ...

Constraining R-parity violating couplings from B --> PP decays using QCD improved factorization method [PDF]

, 2001
We investigate the role of R-parity violating interaction in the non-leptonic decays of B mesons into two light mesons B --> PP. The decay amplitudes are calculated using the QCD improved factorization method.

Pion couplings to the scalar $$B$$ B meson [PDF]

The European Physical Journal C, 2015
We present two-flavor lattice QCD estimates of the hadronic couplings $g_{B^*_0 B π}$ and $g_{B_1^* B_0^* π}$ that parametrise the non leptonic decays $B^*_0 \to B π$ and $B^*_1 \to B_0^* π$. We use CLS two-flavour gauge ensembles. Our framework is the Heavy Quark Effective Theory (HQET) in the static limit and solving a Generalized Eigenvalue Problem (

Classifying avian drinking behaviour: ecological insights and implications in a changing world

Biological Reviews, EarlyView.
ABSTRACT Water is a fundamental currency of life, and its availability significantly influences animal behaviour, physiology and distributions. However, our knowledge around the dependence on water for drinking and the direct and indirect mechanisms driving related behaviours remains partial in the context of changing climates. Here, we review patterns

Tensor hybrid mesons b‾gc

Physics Letters B
Spectroscopic parameters and widths of the tensor hybrid mesons Hbc and H˜bc with the structure b‾gc and spin-parities JP=2− and JP=2+ are calculated with high accuracy in the QCD sum rule framework. Information on their masses m=(7.214±0.075)GeV and m˜=(
