Exploring Non-Holomorphic Soft Terms in the Framework of Gauge Mediated Supersymmetry Breaking

It is known that in the absence of a gauge singlet field, a specific class of supersymmetry (SUSY) breaking non-holomorphic (NH) terms can be soft breaking in nature so that they may be considered along with the Minimal Supersymmetric Standard Model (MSSM) and beyond. There have been studies related to these terms in minimal supergravity based models. Consideration of an F-type SUSY breaking scenario in the hidden sector with two chiral superfields however showed Planck scale suppression of such terms. In an unbiased point of view for the sources of SUSY breaking, the NH terms in a phenomenological MSSM (pMSSM) type of analysis showed a possibility of a large SUSY contribution to muon $g-2$, a reasonable amount of corrections to the Higgs boson mass and a drastic reduction of the electroweak fine-tuning for a higgsino dominated $\widetilde{\chi}^0_1$ in some regions of parameter space. We first investigate here the effects of the NH terms in a low scale SUSY breaking scenario. In our analysis with minimal gauge mediated supersymmetry breaking (mGMSB) we probe how far the results can be compared with the previous pMSSM plus NH terms based study. We particularly analyze the Higgs, stop and the electroweakino sectors focusing on a higgsino dominated $\widetilde{\chi}^0_1$ and $\widetilde{\chi}^{\pm}_1$, a feature typically different from what appears in mGMSB. The effect of a limited degree of RG evolutions and vanishing of the trilinear coupling terms at the messenger scale can be overcome by choosing a non-minimal GMSB scenario, such as one with a matter-messenger interaction.Comment: 27 pages, 9 figures, some text added, results and conclusion unchanged, Accepted in JHE

Ericulture as a Remedy of Rural Poverty in Assam: A Micro Level Study in Barpeta District

Ericulture i.e., rearing of eri cocoon and spinning as well as weaving of endi clothes has been an integral part of the rural economic activities especially of the rural women in Assam. Though both male and female folk of all sections of rural population have been engaged in different sericulture activities, tribal women have been predominant in the rearing and weaving of eri raw silk and endi textiles, who in addition to their daily household activities use their leisure time and with the help of their traditionally inherited knowledge produce useful but comparatively cheaper endi clothes. The activities not only help to increase their household income but also help many of them to come out of the acute poverty. Moreover, these women become economically and thus socially more empowered. An attempt is made in this paper to throw some light on the role of ericulture and endi-entrepreneurship in the generation of income, employment and removal of poverty in Assam.Ericulture, Poverty eradication, Rural entrepreneurship

Silence of the genes- 2006 nobel prize in physiology or medicine

The 2006 Nobel Prize in Physiology or Medicine was awarded to Andrew Fire and Craig Mello for discovering "RNA interference-genesilencing by double-stranded RNA". The Nobel Committee at the Karolinska Institute in Sweden selected them for the award for unraveling "a fundamental mechanism for controlling the flow of genetic information" that is "already being widely used in basic science as a method to study the function of genes and may lead to novel therapies in the future". This has been one of the fastest Nobel Prizes conferred in physiology or medicine, considering that Fire and Mello published their path-breaking article in the journal Nature in 1998, less than ten years ago

AN OUTLOOK AND SPECIALIZED OPINION ON AQUATIC FOOD CHAIN

Food chain is the Linkages of organisms within an ecosystem, in which each link feeds on the one before it and is fed on by the one after it. Only the first link in the chain (called herbage) is a producer and all the rest are consumers. Different food chains intertwine with one another and form the intricate networks called food webs. Nature maintains itself through maintaining a quantitative balance between living species via food chain. First of all Food chain and Food web concepts were introduced in a book published in year 1927 by Charles Elton

Towards chiral diamines as chiral catalytic precursors for the borane-mediated enantioselective reduction of prochiral ketones

Two chiral diamines (3S)-3-anilinomethyl-1,2,3,4-tetrahydroisoquinoline (1) and (2R)-2-anilinomethylpiperidine (2) have been employed as chiral catalytic sources in the borane-mediated asymmetric reduction of prochiral ketones thus providing the resulting secondary alcohols in good enantiomeric purities (up to 81% ee)
