This paper describes the physics case for a new fixed target facility at CERN SPS. The SHiP (Search Hidden Particles) experiment is intended to hunt in largely unexplored domain of very weakly interacting particles with masses below Fermi scale, inaccessible LHC experiments, and study tau neutrino physics. same proton beam setup can be used later look decays tau-leptons lepton flavour number non-conservation, $\tau\to 3\mu$ search weakly-interacting sub-GeV dark matter candidates.

We perform an extensive survey of non-standard Higgs decays that are consistent with the 125 GeV Higgs-like resonance. Our aim is to motivate a large set new experimental analyses on existing and forthcoming data from Large Hadron Collider (LHC). The explicit search for exotic presents largely untapped discovery opportunity LHC collaborations, as such may be easily missed by other searches. emphasize uniquely sensitive potential existence weakly coupled particles provide unified discussion...
High-energy colliders offer a unique sensitivity to dark photons, the mediators of broken U(1) gauge theory that kinetically mixes with Standard Model (SM) hypercharge. Dark photons can be detected in exotic decay 125 GeV Higgs boson, h -> Z Z_D 4l, and Drell-Yan events, pp ll. If is by hidden-sector mechanism, then mixing between SM bosons also allows 4l. We show 14 TeV LHC 100 proton-proton collider provide powerful probes both channels. In case kinetic alone, direct production offers best...
The discovery of the Higgs boson in 2012, by ATLAS and CMS experiments, was a success achieved with only percent entire dataset foreseen for LHC. It opened landscape possibilities study properties, Electroweak Symmetry breaking Standard Model general, as well new avenues probing physics beyond Model. Six years after discovery, conspicuously larger collected during LHC Run 2 at 13 TeV centre-of-mass energy, theory experimental particle communities have started meticulous exploration potential...
Long-lived particles (LLPs) are a common feature in many beyond the Standard Model theories, including supersymmetry, and generically produced exotic Higgs decays. Unfortunately, no existing or proposed search strategy will be able to observe decay of non-hadronic electrically neutral LLPs with masses above $\sim$ GeV lifetimes near limit set by Big Bang Nucleosynthesis (BBN), $c \tau \lesssim 10^7 - 10^8$~m. We propose MATHUSLA surface detector concept (MAssive Timing Hodoscope for Ultra...
Abstract The Physics Beyond Colliders initiative is an exploratory study aimed at exploiting the full scientific potential of CERN’s accelerator complex and infrastructures through projects complementary to LHC other possible future colliders. These will target fundamental physics questions in modern particle physics. This document presents status proposals presented framework Standard Model working group, explore their reach impact that CERN could have next 10–20 years on international landscape.
This report of the BOOST2012 workshop presents results four working groups that studied key aspects jet substructure. We discuss potential first-principle QCD calculations to yield a precise description substructure jets and study accuracy state-of-the-art Monte Carlo tools. Limitations experiments' ability resolve are evaluated, with focus on impact additional (pile-up) proton collisions performance in future LHC operating scenarios. A final section summarizes lessons learnt from analyses...
We examine the theoretical motivations for long-lived particle (LLP) signals at LHC in a comprehensive survey of Standard Model (SM) extensions. LLPs are common prediction wide range theories that address unsolved fundamental mysteries such as naturalness, dark matter, baryogenesis and neutrino masses, represent natural generic possibility physics beyond SM (BSM). In most cases LLP lifetime can be treated free parameter from $\mu$m scale up to Big Bang Nucleosynthesis limit $\sim 10^7$m....
Particles beyond the Standard Model (SM) can generically have lifetimes that are long compared to SM particles at weak scale. When produced experiments such as Large Hadron Collider (LHC) CERN, these long-lived (LLPs) decay far from interaction vertex of primary proton-proton collision. Such LLP signatures distinct those promptly decaying targeted by majority searches for new physics LHC, often requiring customized techniques identify, example, significantly displaced vertices, tracks with...
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...

Offering combination unprecedented collisions comparatively clean leptonic environment, high has unique potential to provide both precision measurements and highest reach one machine that cannot be paralleled by any currently available technology.

A bstract Electroweak Baryogenesis (EWBG) is a compelling scenario for explaining the matter-antimatter asymmetry in universe. Its connection to electroweak phase transition makes it inherently testable. However, completely excluding this can seem difficult practice, due sheer number of proposed models. We investigate possibility postulating “no-lose” theorem testing EWBG future e + − or hadron colliders. As first step we focus on factorized picture which separates sources stronger from...
Over the past decade, a large number of jet substructure observables have been proposed in literature, and explored at LHC experiments. Such attempt to utilize internal structure jets order distinguish those initiated by quarks, gluons, or boosted heavy objects, such as top quarks W bosons. This report, originating from motivated BOOST2013 workshop, presents original particle-level studies that aim improve our understanding relationships between observables, their complementarity, dependence...
This report summarises the physics opportunities in search and study of beyond Standard Model at a 100 TeV pp collider.
The consequences of phase transitions in the early universe are becoming testable a variety manners, from colliders physics to gravitational wave astronomy. In particular one transition we know of, electroweak (EWPT), could potentially be first order BSM scenarios and near future. If confirmed this provide mechanism for baryogenesis, which is most important outstanding questions physics. To reliably make predictions it necessary have full control finite temperature scalar potentials....
Solutions to the hierarchy problem usually require top partners. In standard SUSY or composite Higgs theories, partners carry SM color and are becoming increasingly constrained by LHC searches. However, theories like Folded (FS), Twin (TH) Quirky Little (QLH) introduce uncolored partners, which can be singlets electroweak charge. Their small production cross section left doubt as whether effectively probe such scenarios. Typically, these charged under their own mirror gauge group. FS QLH,...
We propose two simple quirk models to explain the recently reported 750 GeV diphoton excesses at ATLAS and CMS. It is already well known that a real singlet scalar $\ensuremath{\phi}$ with Yukawa couplings $\ensuremath{\phi}\overline{X}X$ vectorlike fermions $X$ mass ${m}_{X}>{m}_{\ensuremath{\phi}}/2$ can easily observed signal, provided carries both SM color electric charge. instead consider first possibility pair production of fermion, charged under gauge groups confining $SU(3{)}_{v}$...
