Open AccessCornering large-Nc QCD with positivity bounds
The simple analytic structure of meson scattering amplitudes in the large-Nc limit, combined with positivity of the spectral density, provides precise predictions on low-energy observables. Building upon previous...

Open AccessTowards a nonperturbative construction of the S-matrix
We present a nonperturbative recipe for directly computing the S-matrix in strongly-coupled QFTs. The method makes use of spectral data obtained in a Hamiltonian framework and can be applied to a wide range of th...

An SQL-Based Declarative Process Mining Framework for Analyzing Process Data Stored in Relational Databases
Recently, the idea of applying process data analysis over relational databases (DBs) has been investigated in the process mining field resulting into different DB schemas that can be used to effectively store ...

Open AccessEarly Post-operative Feeding: An Investigation of Early Functional Outcomes for Oral Cancer Patients Treated with Surgical Resection and Free Flap Reconstruction
Traditionally patients can remain nil by mouth (NBM) for up to 12 days after oral tumour resection with free flap reconstruction to reduce the risk of flap dehiscence, poor healing and fistulae. The literature...

Open AccessImproved BSM sensitivity in diboson processes at linear colliders
We study \(W^+W^-\)W+W- and Zh final sstates at future linear \(e^+e^-\)e+e- colliders; designing analyses specific to the various final state polarizations allows us to target specific beyond the Standard Model ...

Open AccessMassive higher spins: effective theory and consistency
We construct the effective field theory for a single massive higher-spin particle in flat spacetime. Positivity bounds of the S-matrix force the cutoff of the theory to be well below the naive strong-coupling ...

Open AccessElectroweak precision tests in high-energy diboson processes
A promising avenue to perform precision tests of the SM at the LHC is to measure differential cross-sections at high invariant mass, exploiting in this way the growth with the energy of the corrections induced...

Open AccessThe other effective fermion compositeness
We discuss the only two viable realizations of fermion compositeness described by a calculable relativistic effective field theory consistent with unitarity, crossing symmetry and analyticity: chiral-compositenes...

Open AccessPatterns of strong coupling for LHC searches
Even though the Standard Model (SM) is weakly coupled at the Fermi scale, a new strong dynamics involving its degrees of freedom may conceivably lurk at slightly higher energies, in the multi TeV range. Approx...

Open AccessThe last gasp of dark matter effective theory
We discuss an interesting class of models, based on strongly coupled Dark Matter (DM), where sizable effects can be expected in LHC missing energy (MET) searches, compatibly with a large separation of scales. ...

Open AccessDigamma, what next?
If the 750 GeV resonance in the diphoton channel is confirmed, what are the measurements necessary to infer the properties of the new particle and understand its nature? We address this question in the framewo...

Open AccessOn the validity of the effective field theory approach to SM precision tests
We discuss the conditions for an effective field theory (EFT) to give an adequate low-energy description of an underlying physics beyond the Standard Model (SM). Starting from the EFT where the SM is extended ...

Open AccessWhat is the γγ resonance at 750 GeV?
Run 2 LHC data show hints of a new resonance in the diphoton distribution at an invariant mass of 750 GeV. We analyse the data in terms of a new boson, extracting information on its properties and exploring th...

Open AccessRosetta: an operator basis translator for standard model effective field theory
We introduce Rosetta, a program allowing for the translation between different bases of effective field theory operators. We present the main functions of the program and provide an example of usage. One of the L...

Hepatocellular carcinoma in situs ambiguus: CT findings of a rare disposition
Heterotaxic disorders or situs ambiguus are uncommon anatomical variations constituted by a partial mirror-image disposition of intra thoracic and/or abdominal solid organs. These variations are challenging be...

Open AccessModel-independent precision constraints on dimension-6 operators
We discuss electroweak precision constraints on dimension-6 operators in the effective theory beyond the standard model. We identify the combinations of these operators that are constrained by the pole observa...

Open Access(Re-)inventing the relativistic wheel: gravity, cosets, and spinning objects
Space-time symmetries are a crucial ingredient of any theoretical model in physics. Unlike internal symmetries, which may or may not be gauged and/or spontaneously broken, space-time symmetries do not admit an...

Open AccessComposite charge 8/3 resonances at the LHC
In composite Higgs models with partial compositeness, the small value of the observed Higgs mass implies the existence of light fermionic resonances, the top partners, whose quantum numbers are determined by t...

Open AccessTowards the ultimate SM fit to close in on Higgs physics
With the discovery of the Higgs at the LHC, experiments have finally addressed all aspects of the Standard Model (SM). At this stage, it is important to understand which windows for beyond the SM (BSM) physics...

We update the experimental constraints on the parameters of the Higgs effective Lagrangian. We combine the most recent LHC Higgs data in all available search channels with electroweak precision observables fro...
