Abstract The W mass determination at the Tevatron CDF experiment reported a deviation from SM expectation 7 σ level. We discuss few possible interpretations and their collider implications. perform electroweak global fits under various frameworks assumptions. consider three types of in effective-field-theory framework: S - T , eight-parameter flavor-universal one. amoun...

We analyze three-body decays of and . Under the factorization approach, there are tree level diagrams for these decay modes and the transition matrix element of decay is factorized into a form factor multiplied by decay constant and form factor multiplied into weak vertices form factor. The transition matrix element of decay is also factorized into a form factor multiplied into weak vertic...

Access to adequate working capital is often a challenge for SMEs, especially if SME faces the risk of an uncertain yield. We identify conditions under which strong buyer should either offer “backing” or guarantee purchase-order finance cash-constrained, risky supplier, end relationship. By offering backing, shares default faced by bank, in order keep supplier business. To possible benefits this...

We calculate models of stellar evolution for very massive stars and include the effects modified gravity to investigate influence on physical properties blue supergiant their use as extragalactic distance indicators. With shielding fifth force parameters in a similar range previous studies Cepheid tip red giant branch (TRGB) we find clear luminosity flux-weighted gravity. The relationship betwe...
