We provide ingredients and recipes for computing signals of TeV-scale Dark Matter annihilations decays in the Galaxy beyond. For each DM channel, we present energy spectra at production, computed by high-statistics simulations. estimate Monte Carlo uncertainty comparing results yielded Pythia Herwig event generators. then propagation functions charged particles Galaxy, several distribution profiles sets parameters. Propagation e ± is performed with an improved semi-analytic method that takes...
The successful operation of the Large Hadron Collider (LHC) and excellent performance ATLAS, CMS, LHCb ALICE detectors in Run-1 Run-2 with $pp$ collisions at center-of-mass energies 7, 8 13 TeV as well giant leap precision calculations modeling fundamental interactions hadron colliders have allowed an extraordinary breadth physics studies including measurements a variety processes.

This is the third out of five chapters final report [1] Workshop on Physics at HL-LHC, and perspectives HE-LHC [2]. It devoted to study potential, in search for Beyond Standard Model (BSM) physics, High Luminosity (HL) phase LHC, defined as $3~\mathrm{ab}^{-1}$ data taken a centre-of-mass energy $14~\mathrm{TeV}$, possible future upgrade, Energy (HE) $15~\mathrm{ab}^{-1}$ $27~\mathrm{TeV}$. We consider large variety new physics models, both simplified model fashion more model-dependent one....
The HERA electron--proton collider has collected 100 pb$^{-1}$ of data since its start-up in 1992, and recently moved into a high-luminosity operation mode, with upgraded detectors, aiming to increase the total integrated luminosity per experiment more than 500 pb$^{-1}$. been machine excellence for study QCD structure proton. Large Hadron Collider (LHC), which will collide protons centre-of-mass energy 14 TeV, be completed at CERN 2007. main mission LHC is discover mechanisms electroweak...
Searching for heavy vector bosons Z′, predicted in models inspired by Grand Unification Theories, is among the challenging objectives of LHC. The ATLAS and CMS collaborations have looked Z′ assuming that they can decay only into Standard Model channels, set exclusion limits investigating dilepton, dijet and, to a smaller extent, top-antitop final states. In this work we explore possible loopholes these searches, studying supersymmetric as well leptophobic scenarios. We demonstrate existence...

We study the Monte Carlo uncertainties due to modeling of hadronization and showering in extraction top-quark mass from observables that use exclusive hadronic final states top decays, such as $t \rightarrow \text{anything+J/}\psi$ or $t\rightarrow \text{anything}+(B\rightarrow \text{charged tracks})$, where $B$ is a $B$-hadron. To this end, we investigate sensitivity mass, determined by means few already proposed literature well some new proposals, relevant parameters event generators,...
We present an analysis on the production of two same-sign lepton pairs at LHC, mediated by bileptons in $SU(3)_c\times SU(3)_L\times U(1)_X$ theory, so-called 331 model. Compared to other scenarios, this model embedding hypercharge is obtained with addition 3 exotic quarks and doubly-charged vector gauge bosons numbers $\pm 2$ spectrum ($Y^{\pm\pm}$), which can mediate four-lepton final states. Furthermore, a complete description requires introduction Higgs scalar sector, sextet $SU(3)_L$,...
We investigate the production of vector-like quarks with charge $5/3$ at LHC and their subsequent decays into new singly or doubly charged bosons plus a heavy quark (top bottom). In particular, we explore final states same-sign di-leptons (electron muon pairs), leptons coming from decay and, in case bosons, top as well. These processes are predicted by classes models based on extensions gauge group Standard Model, such 331 where electroweak symmetry is described $SU(3)_L\times U(1)_X$, $X$...
We gauge the impact of soft-gluon resummation on quark distributions by performing a simple fit deep inelastic scattering structure function data using next-to-leading order (NLO) and next-to-leading-logarithmic- (NLL)-resummed coefficient functions. make use NuTeV charged-current data, as well New Muon Collaboration (NMC) Bologna-CERN-Dubna-Munich-Saclay (BCDMS) neutral-current results, which probe large values $x$. Our results suggest that inclusion effects in global fits parton is both...

The top-quark mass is a parameter of paramount importance in the Standard Model, playing crucial role electroweak precision tests and stability Model vacuum. I will discuss main strategies to extract at LHC interpretation measurements terms well-posed top-mass definitions, taking particular care about renormalon ambiguities, Monte Carlo event generators theoretical uncertainties.
We discuss the main signatures of Bilepton Model at Large Hadron Collider, focusing on its gauge boson sector. The model is characterised by five additional bosons, four charged and one neutral, beyond those Standard Model, plus three exotic quarks. latter turn into ordinary quarks with emission bilepton doublets $(Y^{++},Y^{+})$ $(Y^{--},Y^{-})$ lepton number $L=-2$ $L=+2$ respectively, doubly-charged bileptons decaying same-sign pairs. perform a phenomenological analysis investigating...
