The TESLA Technical Design Report Part III: Physics at an e+e- Linear Collider
The Large Hadron electron Collider (LHeC) is designed to move the field of deep inelastic scattering (DIS) energy and intensity frontier particle physics. Exploiting recovery technology, it collides a novel, intense beam with proton or ion from High Luminosity--Large (HL-LHC). accelerator interaction region are for concurrent electron-proton proton-proton operation. This report represents an update Conceptual Design Report (CDR) LHeC, published in 2012. It comprises new results on parton...
We present the activities of `New Physics' working group for `Physics at TeV Colliders' workshop (Les Houches, France, 5--23 June, 2017). Our report includes new physics studies connected with Higgs boson and its properties, direct search strategies, reinterpretation LHC results in building viable models computational tool developments.
Abstract The field of particle physics is at the crossroads. discovery a Higgs-like boson completed Standard Model (SM), but lacking observation convincing resonances Beyond SM (BSM) offers no guidance for future physics. On other hand, motivation New Physics has not diminished and is, in fact, reinforced by several striking anomalous results many experiments. Here we summarise status most significant anomalies, including recent flavour multi-lepton anomalies LHC, excess around 96 GeV,...
High energy photon colliders (γγ,γe) are based on e - linear where high photons produced using Compton scattering of laser light electrons just before the interaction point. This paper is a part Technical Design Report collider TESLA. 1 Physics program, possible parameters and some technical aspects at TESLA discussed.
We investigate methods to explore the $CP$ nature of $t\overline{t}h$ coupling at LHC, focusing on associated production Higgs boson with a $t\overline{t}$ pair. first discuss constraints implied by low-energy observables and Higgs-rate information from available LHC data, emphasizing that they cannot provide conclusive evidence this coupling. then kinematic could probe directly, in particular, quantities can be constructed out just laboratory-frame kinematics. define one such observable...
With the renewed interest in vector-like fermion extensions of Standard Model, we present here a study multiple theories and their phenomenological implications. Our focus is mostly on minimal flavor conserving that couple fermions to SM gauge fields mix only weakly with so as avoid problems. We calculations for precision electroweak state decays, which are needed investigate compatibility currently known data. impact Higgs boson production decay, including loop contributions, wide variety...
The search and the probe of fundamental properties Higgs boson(s) and, in particular, determination their charge conjugation parity (CP) quantum numbers, are main tasks future high-energy colliders. We demonstrate that CP a standard model-like particle can be unambiguously assessed by measuring just total cross section top polarization associated boson production with quark pairs e(+)e(-) collisions.
We consider how the measurement of top polarization at Tevatron can be used to characterise and discriminate among different new physics models that have been suggested explain anomalous forward-backward asymmetry reported Tevatron. This has advantage catching essence parity violating effect characteristic models. Other observables constructed from these asymmetries are shown useful in discriminating between models, even after taking into account statistical errors. Finally, we discuss some...
We revisit the constraints on parameter space of Minimal Supersymmetric Standard Model (MSSM), from charge and color breaking minima in light information Higgs LHC so far. study behavior scalar potential keeping two sfermion fields along with pMSSM framework analyze stability vacuum. find that for lightest stop $\lesssim 1$ TeV small $\mu \lesssim 500$ GeV, absolute can be attained only $|X_{t}| \sqrt{ 6 m_{\tilde{t}_1} m_{\tilde{t}_2}}$. The bounds become stronger larger values $\mu$...
Determining the spin and parity quantum numbers of recently discovered Higgs-like boson at LHC is a matter great importance. In this paper, we consider possibility using kinematics tagging jets in Higgs production via vector fusion (VBF) process to test tensor structure Higgs-vector ($HVV$) interaction determine CP properties observed resonance. We show that an anomalous $HVV$ vertex, particular its explicit momentum dependence, drastically affects rapidity between two scattered quarks their...
While the recent discovery of a Higgs-like boson at LHC is an extremely important and encouraging step towards {\it complete} standard model(SM), current information on this state does not rule out possibility beyond model (BSM) physics. In fact data can still accommodate reasonable values branching fractions Higgs into channel with `invisible' decay products, such being also well motivated theoretically. study we revisit detecting in invisible for both choices energies, 8 14 TeV, two...

This Report summarises the activities of "SM and Higgs" working group for Workshop "Physics at TeV Colliders", Les Houches, France, 2-20 May, 2005. On one hand, we performed a variety experimental theoretical studies on standard candles (such as W, Z, ttbar production), treating them either proper signals known physics, or backgrounds to unknown physics; also addressed issues relevant those non-perturbative semi-perturbative ingredients, such Parton Density Functions Underlying Events, whose...
