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...
We present a complete list of the dimension-eight operator basis in standard model effective field theory using group theoretic techniques systematic and automated way. adopt new form operators terms irreducible representations Lorentz identify structures as states $SU(N)$ group. In this way, redundancy from equations motion is absent that integration by part treated fact independent forms an invariant subspace also decompose into ones with definite permutation symmetries among flavor...
We present a complete and independent list of the dimension-nine operator basis in Standard Model effective field theory by an automatic algorithm based on amplitude-operator correspondence. A ($Y$-basis) is first constructed enumerating Young tableau auxiliary $SU(N)$ group gauge groups, with equation-of-motion integration-by-part redundancies all removed. In presence repeated fields, another ($P$-basis) explicit flavor symmetries among them derived from $Y$-basis, which further induces...
We present a general method of constructing unfactorizable on-shell amplitudes (amplitude basis), and build up their one-to-one correspondence to the independent complete operator basis in effective field theory (EFT). apply our Standard Model EFT, identify amplitude dimension 5 6, which correspond Weinberg operators Warsaw except for some linear combinations.
We study information-theoretic properties of scalar models containing two Higgs doublets ${\mathrm{\ensuremath{\Phi}}}_{a}$, where $a=1$, 2 is the flavor quantum number. Considering 2-to-2 scattering ${\mathrm{\ensuremath{\Phi}}}_{a}{\mathrm{\ensuremath{\Phi}}}_{b}\ensuremath{\rightarrow}{\mathrm{\ensuremath{\Phi}}}_{c}{\mathrm{\ensuremath{\Phi}}}_{d}$ as a two-qubit system in subspace and $S$-matrix logic gate, we analyze entanglement power at tree level, limit gauge coupling turned off....
We study the holographic complexity of noncommutative field theories. The four-dimensional $\mathcal{N}=4$ super Yang-Mills theory with Moyal algebra along two spatial directions has a well known dual as type IIB supergravity stack D3 branes and non-trivial NS-NS B fields. start from this example find that late time growth rate, based on "complexity equals action" conjecture, experiences an enhancement when non-commutativity is turned on. This saturates new limit which exactly 1/4 larger...
We obtain the complete and independent bases of effective operators at mass dimension 5, 6, 7, 8, 9 in both standard model field theory with light sterile right-handed neutrinos ($\nu$SMEFT) low energy ($\nu$LEFT). These theories provide systematical parametrizations on all possible Lorentz-invariant physical effects involving Majorana/Dirac neutrinos, with/without lepton number violations. In $\nu$SMEFT, we find that there are 2 (18), 29 (1614), 80 (4206), 323 (20400), 1358 (243944)...
We derive the generalized partial wave expansion for $N\ensuremath{\rightarrow}M$ scattering amplitude in terms of spinor helicity variables. The basis amplitudes with definite angular momentum $j$ consist Poincar\'e Clebsch-Gordan coefficients. Moreover, we obtain a series selection rules that restrict anomalous dimension matrix effective operators and how contribute to some $2\ensuremath{\rightarrow}N$ at loop level.

The operator-amplitude correspondence tells a type operator forms on-shell amplitude basis, for involved Nambu-Goldstone bosons, basis is further reduced to subspace satisfying Adler zero condition soft momentum limit. Different from dynamical fields, spurion should not enter into...
To avoid possible electroweak vacuum instability in the vectorlike fermion model, we introduce a new singlet scalar to which couples and also mixes with Higgs boson after spontaneous symmetry breaking. We investigate predominantly coupled third-generation quarks, its mass is generated from expectation value of field model. In this setup, as running towards high energies, provides positive contribution quartic coupling, matching on scale gives rise threshold effect that lifts up coupling...
A bstract For the first time, we list complete and independent set of operators at next-to-next-to-leading order (NNLO) in Higgs effective field theory (HEFT). The Young tensor technique utilized this work guarantees completeness independence on-shell amplitude basis while Adler zero condition imposes non-linear symmetry on Nambu-Goldstone bosons that play central role chiral Lagrangian. spurion fields are incorporated into gauge structure following Littlewood-Richardson rule to accommodate...
We establish a systematic construction of the on-shell amplitude/operator basis for Chiral Perturbation Theory (ChPT) in $D=4$ spacetime dimensions and with an arbitrary number flavors $N_f$. For kinematic factors, we employ spinor-helicity variables to construct soft blocks, which are local amplitudes satisfying Adler's zero condition, as well take into account reduction due Gram determinant, arises at $O(p^{10})$ when multiplicity $N$ amplitude becomes large: $N>D$. flavor include...

We find that at fixed temperature increases with angular momentum J/M ℓ . The amount information can be sent through as well. However, for type interaction considered, closes approaches extremal limit. also briefly consider scenario where coupling is not spatially homogeneous and show how reflected opening.

We describe a general procedure to construct the independent and complete operator bases for generic Lorentz invariant effective field theories, given any kind of gauge symmetry content, up mass dimension. By considering as contact on-shell amplitude, so-called amplitude correspondence, we provide unified construction flavor structures by Young Tableau tensor. Several are constructed emphasize different aspects: independence (y-basis m-basis), repeated fields with flavors (p-basis),...
A bstract The effective field theory approach parameterizes the low energy behaviors of all possible ultraviolet (UV) theories in a systematic way. One most important tasks is thus to find connection between operators and their UV origins. redundancy relations among make very subtle, hence we proposed J-basis prescription illuminate correspondence resonances bottom-up In this work, work out dimension-8 standard model (SMEFT), 146 (82) tree-level along with couplings up mass dimension 5 (4)....
We investigate an inflationary model involving a gauge singlet scalar and fermionic dark matter. The mixing between the Higgs boson provides portal to inflaton could either be or scalar, slow roll inflation is realized via its nonminimal coupling gravity. In this setup, effective potential stabilized by two scalars with study constraints from collider searches, relic density direct detection, find that matter mass should around half of scalar. Using renormalization group equation improved...
In the past, study of divergence structure holographic entanglement entropy on singular boundary regions uncovered cut-off independent coefficients. These coefficients were shown to be universal and encode important field theory data. Inspired by these lessons we UV divergences subregion complexity-action (CA) in a region with corner (kink). We develop systematic approach all structures, emphasize that counter term restores reparameterization invariance null boundaries plays crucial role...

The independence of basis regarding equation motion, integration by parts flavor relations, is guaranteed our algorithm [1, 2], whose validity LEFT with massive fermions involved proved a generalization amplitude-operator correspondence. At dimension 8 9, we list 35058 (756) 704584...
We extend the standard model to a scalar-assisted vectorlike fermion realize electroweak baryogenesis. The extended Cabibbo-Kobayashi-Maskawa matrix, due mixing among quark and quarks, provides additional sources of $CP$ violation. Together with enhancement from large mass, enough baryon-to-photon ratio could be obtained. strongly first-order phase transition realized via potential barrier which separates broken minimum symmetric in scalar potential. investigate detail one loop...
We construct the general partial wave amplitude basis for $N\ensuremath{\rightarrow}M$ scattering, which consists of Poincar\'e Clebsch-Gordan coefficients, in a Lorentz invariant form given terms spinor-helicity variables. The inner product coefficients is defined, converts on-shell phase space integration into an algebraic problem. also develop technique expansions arbitrary amplitudes, including those with infrared divergence. These are applied to computation anomalous dimension matrix...
