Very light sbottom and gluino scenario confronting electroweak precision tests
The minimal supersymmetric model with light sbottom (∼ mb) and light gluino (12 ∼ 16 GeV) can explain the excess of bottom quark production cross section at hadron colliders and has drawn much attention. We calculate one-loop contribution to Z-pole observable Rb in this scenario when large CP violating phases are allowed in the gluino mass and/or sbottom sector. We show that these large CP viol...
متن کاملChasing the light - gluino scenario through b → sγ
We investigate the impact of a light gluino, which might have escaped detection at colliders, on inclusive radiative B-decays mediated through penguin-like diagrams. We find that the viability of the scenario depends largely on the magnitude of the flavour-violating c-parameter. Some previously allowed regions of parameter space are now ruled out.

متن کاملThe light sbottom mass window revisited
An apparent excess of more than 4σ in the e+e− → hadron cross section for centre-of-mass energies between 20 to 209GeV has recently been reported. This excess was found to be well reproduced over the whole energy range by the production of a pair of sbottoms with mass 6GeV/c2 and mixing angle cos θmix = 0.18. It is shown here that the reported excess essentially vanishes after the implementatio...
متن کاملLight Gluino and Tevatron Data
A very light gluino (mg̃< ∼2GeV) is still consistent with experimental data and is attractive from a theoretical standpoint. This has been shown to lead to a small gluino content of the proton. We use this effect to demonstrate that such a light gluino could lead to a striking enhancement, at Tevatron, of monojets accompanied by large missing momentum. A reanalysis of the existing data may thus ...

عصر روشنگری زمان شکل گیری ایده های مدرن تربیتی- آموزشی بود اما تاکید بیش از اندازه ی دوشاخه مهم فلسفی زمان یعنی عقل گرایی و حس گرایی بر دقت و وضوح، انسان عصر روشنگری را نسبت به دیگر تواناییهایش نابینا کرده و موجب به وجود آمدن افرادی تک بعدی شد که افتخارعقلانیتشان، تاکید شان بر تجربه فردی، به مبارزه طلبیدن منطق نیاکانشان وافسون زدایی شان از دنیا وتمام آنچه با حواس پنجگانه قابل درک نبوده و یا در ...
