We present a comprehensive review of physics effects generated by leptoquarks (LQs), ie,
hypothetical particles that can turn quarks into leptons and vice versa, of either scalar or …

Half a century after its formulation, the Standard Model (SM) is by now the established theory
of Electro-Weak (EW) and Strong interactions, the discovery of the Higgs boson being the …

The ratio of the measured B¯→ D (*) ℓ ν¯ decay rates for ℓ= τ vs e, μ deviate from the
standard model (SM) by about 4 σ. We show that the data are in tension with the SM …

After the discovery of the top quark more than 20 years ago, its properties have been studied
in great detail both in production and in decay. Increasingly sophisticated experimental …

A bstract We classify the four-dimensional purely fermionic gauge theories that give a UV
completion of composite Higgs models. Our analysis is at the group theoretical level …

We adopt a fully gauge-invariant effective-field-theory approach for parametrizing top-quark
flavor-changing-neutral-current interactions. It allows for a global interpretation of …

We present the activities of the" New Physics" working group for the" Physics at TeV
Colliders" workshop (Les Houches, France, 30 May-17 June, 2011). Our report includes new …

A search has been performed for pair production of heavy vectorlike down-type (B) quarks.
The analysis explores the lepton-plus-jets final state, characterized by events with one …

Results of a search for new phenomena in events with at least three photons are reported.
Data from proton–proton collisions at a centre-of-mass energy of 8 TeV, corresponding to an …

A bstract Relatively light Top Partners are unmistakable signatures of reasonably Natural
Composite Higgs models and as such they are worth searching for at the LHC. Their …
