Bi-epicondylar avulsion fracture of the distal humerus is a rare injury and poses challenges for treating orthopaedic surgeons. We present a case of 11-year-old boy who presented with bi-epicondylar avulsion fractures of the distal humerus that was m

Background: Genu valgum is a common deformity in the developing world. When the patient presents after a second growth spurt, corrective surgery remains the only treatment option. Different types of osteotomies and fixation methods have been describe

Weak radiative B-meson decay has been studied to find plausible constraints on the complex coupling constants that arise from the diagonalization of the charged scalar mixing matrix in Weinberg three-Higgs-doublet model considering possibility of the

We investigate how the vector meson dominance affects the O(αs) virtual corrections in addition to the bremsstrahlung correction while working out the matrix elements for b→sγ and b→ dγ decays. Long-distance effect alone is not appreciable but

The parity conserving (PC) and the parity violating (PV) coupling constants are evaluated by considering the PC and PV poles and these coupling constants are respectively given by: C=1.12× 10-7 and D=1.15× 10-7. Using these coupling constants we ha

The effective $tcZ$ vertex may be influenced by tree $dd^\prime Z$ vertex formed by a mixing with heavy exotic isosinglet down type quarks. To study that the electroweak penguin diagrams involving one insertion of the $dd^\prime Z$ vertex have been c

In our letter we deal with the inclusive and exclusive decay of B- meson. The inclusive b→dγ decay has been considered here including the QCD corrections to the Wilson coefficients and the matrix elements of the operators in the effective Hamilton

Radiative B decays provide valuable information on some poorly known CKM matrix elements |Vtb| and |Vts|. So in our letter we propose to study the flavor changing radiative B decays corresponding to the inclusive b→ sγ and b→dγ decays. In this

We extend the SU(3) mixing of isosinglet pseudoscalar mesons to the SU(4) level with η, η′, ηc and ι. The quarkonium gluonium content of the physical states at the SU(4) level are being numerically estimated. We derive a mass relation at the SU

From the pole dominance approximation for\(D^0 - \bar D^0 \)transformation an estimate of the ΔMd or the mass difference of DL0 and Ds0 meson has been found out. The results obtained are close to that of Donoghue et al. Two gamma decay width of D0 m
