Isospin symmetry breaking (ISB) effects in the charge radius difference $\mathrm{\ensuremath{\Delta}}{R}_{\mathrm{ch}}$ of mirror nuclei are studied using test example $^{48}\mathrm{Ca}$ and $^{48}\mathrm{Ni}$. This choice allows for a transparent study ISB contributions since pairing deformation effects, commonly required nuclei, can be neglected this specific pair. The connection with nuclear...

Recent results are presented for (1) the charge asymmetry in semielectronic kaon decay; (2) the charge radius of the neutral kaon; (3) the decay K 0 L → π 0 π 0 e + e − ; (4) constraints on ρCKM from kaon decays; (5) lepton flavor violation. A few words about future kaon physics work at Fermilab are included.

This paper reviews calculations of the electromagnetic properties of baryons using the constituent quark model. We start with a short discussion of spontaneous chiral symmetry breaking, which is essential in understanding the transition from QCD to the constituent quark model. We then discuss a chiral version of the constituent quark model, which simulates the symmetries and dynamical content o...

In this paper we describe a novel method for delivering a precise, known amount of electric charge to a micron-sized solid target. Aerosolised microparticles passed through a plasma discharge will acquire significant electric charge. The fluid stability under evaporative stress is a key aspect that is core to the research. Initially stable charged aerosols subject to evaporation (i.e. a continu...

In this study, we have mapped the surface charge of wool fibers using chemically specific high-resolution force spectroscopy in order to better understand the dispersion of amino acids in relation to fiber morphology. The inter-surface forces between standard atomic force microscopy (AFM) probe tips (tip radius ~ 50 nm) functionalized with COOH and NH(3) terminated alkanethiol self assembling m...

This paper is about the extended thermodynamics of AdS black holes and its relation to CFT thermodynamics. The logarithmic term central charge interpreted as hole entropy. We have obtain a modified Friedmann equation from Smarr formula. find that radius critical shadow radius. Hawking-Bekenstein formula with corrections, which depends on charge. real gas in dual an ideal CFT. work can be AdS-Ke...

Coulomb and charge-symmetry breaking effects in the He ground state within the dressed dibaryon model developed recently for 2N and 3N forces are examined in detail. Particular attention has been paid to the Coulomb displacement energy ∆EC = EB( H) − EB(He) and rms charge radii of H and He. A new scalar 3N force between the third nucleon and dibaryon is found to be very important for a correct ...

The current status of the determination of corrections to the hyperfine splitting of the ground state in hydrogen is considered. Improved calculations are provided taking into account the most recent value for the proton charge radius. Comparing experimental data with predictions for the hyperfine splitting, the Zemach radius of the proton is deduced to be 1.045(16) fm. Employing exponential pa...
