    The study on the prospects of strawberry cultivation by the strawberry growers indicated that overall prospects of strawberry cultivation were medium to high since 78 percent belonged to these categories. The study was conducted in Bhiwani and Hisar districts. Prospects were categorized into two categories i.e. production related prospects and general prospect of strawberry cultivation. Majority of farmers agreed that demand is increasing day by day (weighted mean score 2.78) which is an indication of innovativeness (weighted mean score 2.76), status in village (weighted mean score 2.68). The purchasing power of people  increased (weighted mean score 2.64) The  better economic returns in comparison to other fruit crops (weighted mean score 2.62) and high nutritious value of fruit (weighted mean scores 2.62) were osberved.  In case Govt. provides facilities, it would take the persons to go for strawberry cultivation (weighted mean score 2.58). The food habit of people changed (weighted mean score 2.54). The high price (weighted mean score 2.52) was suitable for agro-processing (weighted mean score 2.5), whereas better export facilities available (weighted mean score 1.88), farmer friendly being easy to produce (weighted mean score 1.56), better market facilities available at present (weighted mean score 1.52) and better technical support available(weighted mean score 1.44) were not upto the desired level of prospects as perceived by strawberry growers

    The survey based study focused on adoption level of strawberry growers with respect to package of practices of strawberry was conducted in Hisar and Bhiwani districts of Haryana. The adoption level was measured by scores on the basis of adoption level. While analyzing, the magnitude of adoption level adopted by strawberry growers revealed that method of propagation and packaging (100%), timely irrigation (95.33%), proper time of planting (90%), varieties used for planting (86.67%) , proper planting depth (86%), mulching (85.33%) was adopted by majority of farmers whereas manures and fertilizers and diseases and their control(71.34%), intercultural operations (63.33%) and control measures for fruit drop (55.33%) were least adopted

    Get PDF
    Sherpa is a general-purpose Monte Carlo event generator for the simulation of particle collisions in high-energy collider experiments. We summarize essential features and improvements of the Sherpa 2.2 release series, which is heavily used for event generation in the analysis and interpretation of LHC Run 1 and Run 2 data. We highlight a decade of developments towards ever higher precision in the simulation of particle-collision events

    Constraints on the χ_(c1) versus χ_(c2) polarizations in proton-proton collisions at √s = 8 TeV

    The polarizations of promptly produced χ_(c1) and χ_(c2) mesons are studied using data collected by the CMS experiment at the LHC, in proton-proton collisions at √s=8  TeV. The χ_c states are reconstructed via their radiative decays χ_c → J/ψγ, with the photons being measured through conversions to e⁺e⁻, which allows the two states to be well resolved. The polarizations are measured in the helicity frame, through the analysis of the χ_(c2) to χ_(c1) yield ratio as a function of the polar or azimuthal angle of the positive muon emitted in the J/ψ → μ⁺μ⁻ decay, in three bins of J/ψ transverse momentum. While no differences are seen between the two states in terms of azimuthal decay angle distributions, they are observed to have significantly different polar anisotropies. The measurement favors a scenario where at least one of the two states is strongly polarized along the helicity quantization axis, in agreement with nonrelativistic quantum chromodynamics predictions. This is the first measurement of significantly polarized quarkonia produced at high transverse momentum

    Report from Working Group 3: Beyond the standard model physics at the HL-LHC and HE-LHC

    This is the third out of five chapters of the final report [1] of the Workshop on Physics at HL-LHC, and perspectives on HE-LHC [2]. It is devoted to the study of the potential, in the search for Beyond the Standard Model (BSM) physics, of the High Luminosity (HL) phase of the LHC, defined as 33 ab1^{-1} of data taken at a centre-of-mass energy of 14 TeV, and of a possible future upgrade, the High Energy (HE) LHC, defined as 1515 ab1^{-1} of data at a centre-of-mass energy of 27 TeV. We consider a large variety of new physics models, both in a simplified model fashion and in a more model-dependent one. A long list of contributions from the theory and experimental (ATLAS, CMS, LHCb) communities have been collected and merged together to give a complete, wide, and consistent view of future prospects for BSM physics at the considered colliders. On top of the usual standard candles, such as supersymmetric simplified models and resonances, considered for the evaluation of future collider potentials, this report contains results on dark matter and dark sectors, long lived particles, leptoquarks, sterile neutrinos, axion-like particles, heavy scalars, vector-like quarks, and more. Particular attention is placed, especially in the study of the HL-LHC prospects, to the detector upgrades, the assessment of the future systematic uncertainties, and new experimental techniques. The general conclusion is that the HL-LHC, on top of allowing to extend the present LHC mass and coupling reach by 2050%20-50\% on most new physics scenarios, will also be able to constrain, and potentially discover, new physics that is presently unconstrained. Moreover, compared to the HL-LHC, the reach in most observables will, generally more than double at the HE-LHC, which may represent a good candidate future facility for a final test of TeV-scale new physics
