DESCRIPTION:Speakers: Thomas Flacke (KAIST)\nComposite Higgs Models predic
t quark partners at the TeV scale which can be produced at the LHC Run II.
The decay of such heavy quark partners lead to highly boosted objects in
the final state (e.g. tops\, Higgses and electroweak gauge bosons) which r
equire refined search strategies. In this talk we propose boosted object s
earches which utilizes a simplified b-tagging procedure and the Template
Overlap Method to tag the massive boosted objects and reject the correspon
ding backgrounds. In addition\, we propose a new\, pileup insensitive meth
od\, to tag forward jets which characterize our signal events. We show tha
t this search strategy offers a new window to both detecting and measurin
g quark partners of mass up to ~ 2 TeV.\n \nBased on: \nM.Backović

DESCRIPTION:Speakers: Mads Frandsen (CP3 Origins)\nIn this talk I study a
simple\, experimentally viable effective Lagrangian\, the Custodial Vector
Model with symmetries protecting the (composite) Higgs couplings and the
values of the electroweak parameters - Essentially the 'degenerate-BESS' m
odel with a Higgs state. I will use this model as a basis to discuss how u
nderlying strong dynamics may give rise to SM Higgs like state at LHC. \n\

DESCRIPTION:Speakers: Oleg Antipin (INFN & Firenze U.)\nAssuming that mass
scales arise in nature only via dimensional transmutation\, we extend th
e dimension-less Standard Model by adding vector-like fermions charged und
er a new strong gauge interaction. Their non-perturbative dynamics genera
tes a mass scale that is transmitted to the elementary Higgs boson by ele
ctro-weak and possibly Yukawa interactions. In its minimal version the mo
del has the same number of parameters as the Standard Model and predicts
that the electro-weak symmetry gets broken and predicts new-physics in the
multi-TeV region which is compatible with all existing bounds. It also pr
ovides two Dark Matter candidates stable thanks to accidental symmetries:
a composite scalar in the adjoint of SU(2)_L and a composite singlet fermi
on. Their thermal relic abundance is predicted to be comparable to the mea
sured cosmological DM abundance. \n\nBased on: O.Antipin\, M.Redi\, and A

DESCRIPTION:Speakers: Seung Joon Lee (KAIST)\nWe study a model in which da
rk matter couples to the Standard Model through a dilaton of a sector with
spontaneously broken approximate scale invariance. Scale invariance fixes
the dilaton couplings to the standard model and dark matter fields\, leav
ing only three free parameters: the symmetry breaking scale f\, the dilato
n mass m_dilaton \, and the dark matter mass m_DM. One of these parameters
is further fixed by requiring that thermal freeze-out results in the obse
rved dark matter relic abundance. We show that a large parametric region e
xists where the effective theory is perturbative and produces cold\, weakl
y interacting massive particle dark matter\, with f\, m_dilaton\, m_DM of
roughly similar magnitude and in the range ~1-10 TeV. We analyze the exper
imental constraints on the parameter space from collider\, direct and indi
rect detection experiments\, and demonstrate that dilaton exchange provide
s a consistent\, calculable framework for cold dark matter.\n\nBased on: K

SUMMARY:Towards Constraining Composite Higgs Models via the Bootstrap

DESCRIPTION:Speakers: Marco Serone (SISSA)\nWe discuss how the bootstrap a
pproach can be used to possibly set constraints on composite Higgs models\
, where the strongly coupled sector is assumed to be a spontaneously broke
n CFT with a global symmetry. As a preliminary step in this direction\, we
analyze the bounds on the OPE coefficients of the conserved vector curren
ts associated with the groups SO(N)\, SU(N) and SO(N)xSO(M) under the assu
mption that in the singlet channel no scalar operator has dimension less t
han four\, namely that the CFT has no relevant deformations. These OPE coe
fficients govern the leading CFT contribution to the RG evolution of the a
ssociated gauge couplings.\n\nhttps://indico.in2p3.fr/event/10617/contribu

DESCRIPTION:Speakers: Gabriele Ferretti (Chalmers U.)\nWe present some fou
r-dimensional purely fermionic gauge theories that\ngive a UV completion o
f composite Higgs models. We start at the group theoretical level\, addres
sing the necessary (but not sufficient) conditions for the viability of th
ese models\, such as the existence of top partners and custodial symmetry.
We then study the dynamics of one of the most promising models\, based on
a SU(4) hyper-color group in more detail.\n\nWork based on JHEP 1403 (201

SUMMARY:A Unified Approach to Composite Dynamics: from Electroweak Symmetr

DESCRIPTION:Speakers: Francesco Sannino (CP3 Odense)\nCirca 95% of the uni
verse is made of unknown forms of matter and energy\, while to describe th
e remaining 5% one needs at least three fundamental forces\, i.e. Quantum
Electrodynamics (QED)\, Weak Interactions and Quantum Chromo Dynamics (QCD
). Furthermore strong interactions are responsible for creating the bulk o
f the bright mass\, i.e. the 5%. It is therefore natural to expect that to
correctly describe the rest of our universe while providing a sensible li
nk to the visible component new forces will soon emerge. For example the s
tandard model sector responsible for breaking the electroweak symmetry spo
ntaneously could be replaced by a new and more natural strongly coupled se
ctor. Another interesting avenue is the possibility that dark matter itsel
f\, as the ordinary proton and neutron\, is not an elementary particle but
rather a state composed by new strongly coupled matter. I will argue that
models of composite dynamics are indeed primary candidates for a better u
nderstanding of the origin of bright and dark matter in Nature. I will als
o show that we can make clear and falsifiable predictions for the Large Ha
dron Collider experiment as well as dark matter direct experiments searche
s. Understanding strong dynamics is therefore crucial to construct phe
nomenologically relevant extensions of the standard model of particle inte
ractions\, and ultimately being able to describe our Universe.\n\nhttps://
