Abstract We present the DMSimpt model implementation in FeynRules. which aims to offer a unique general framework allowing for all simulations relevant for simplified t-channel dark matter models at colliders and for the complementary cosmology calculations. We describe how to match next-to-leading-order QCD fixed-order calculations with parton showers to derive robust bounds and pred... https://cosmeticssquadets.shop/product-category/back-scratchers/
