A search for direct production of C-even resonances a2(1320) and f2(1270) in e e annihilation was performed with SND detector at VEPP-2M ee collider. The upper limits of electronic widths of these mesons were obtained at 90% confidence level: Γ(a2(1320) → e e) <0.56 eV, Γ(f2(1270) → e e) <0.11 eV. PACS: 13.40.Gp; 13.65.+i; 13.85.Rm; 14.40.Cs

Bilindiği üzere, Secâvendî vakfı; lâzım ( م ), mutlak ط caiz ج mücevvez li-vechin ز murahhas zarureten ص ) ve gayr-ı câiz لا olmak üzere altı kategoriye ayırmış bu kategorileri parantez arasında belirttiğimiz harflerden belirlediği sembollerle göstermiştir. Türkiye’deki mushaflarda Secâvendî’nin sistemi tercih edilmiş olmasına rağmen, onun sisteminde bulunmayan kimi rumuzlar da kullanılmıştır. ...

MicroRNAs (miRNAs or miRs) are a class of short non-coding RNAs that serve an important regulatory role in living organisms. These molecules are associated with multiple biological processes and are potential biomarkers in multiple diseases. The present study aimed to further identify miRNAs that are differentially expressed in circulating monocytes (CMCs) from postmenopausal Mexican-Mestizo wo...

We point out that hard exclusive production of tensor mesons f 2 (1270) with helicity λ = ±2 is dominated by the gluon component in the meson wave function and can be used to determine gluon admixture in tensor mesons in a theoretically clean manner. We present a detailed analysis of the tensor meson distribution amplitudes and calculate the transition form factor γ + γ * → f 2 (1270) for one r...

The rare decay $B\rightarrow A\gamma$, with $A$ representing axial-vector mesons such as $K_1 (1270),\; K_1 (1400),\; b_1(1300),\; a_1(1260)$, is studied at next-to-leading order (NLO) in soft collinear effective theory (SCET). large outgoing meson energy encourages the study of an appropriate factorization scheme that separates factorizable and non-factorizable parts systematically. We have an...
