We derive the third subleading (N$^3$LO) corrections of quadratic-in-spin sectors via EFT spinning objects in post-Newtonian (PN) gravity. These consist contributions from $4$ for generic compact binaries, that enter at fifth PN order. One these is due to a new tidal interaction, unique with spin, and complements first interaction also enters this order simple point-mass sector. The evaluation Feynman graphs carried out dimension advanced multi-loop methods, gives rise...
A bstract We put forward a broader picture of the effective theory spinning particle within EFT gravitating objects, through which we derive and establish new precision frontier at fifth PN (5PN) order. This includes higher-spin sectors, quadratic quartic in spin, both display novel physical features, due to extension beyond linear order curvature. The quadratic-in-spin sectors give rise tidal effect, quartic-in-spin exhibit multipolar deformation. then generalize concept operators...
A bstract We present the derivation of third subleading order (N 3 LO) spin-orbit interaction at state art post-Newtonian (PN) gravity via EFT spinning objects. The sector contains largest and most elaborate collection Feynman graphs ever tackled to date in sectors with spin, all PN up order. Our computations are carried out advanced multi-loop methods. Their demanding aspect is imperative transition a generic dimension across whole derivation, due emergence dimensional-regularization poles...
The Compact Linear Collider (CLIC) is a mature option for the future of high energy physics. It combines benefits clean environment $e^+e^-$ colliders with operation at centre-of-mass energies, allowing to probe scales beyond reach Large Hadron (LHC) many scenarios new This places CLIC project privileged spot in between precision and frontiers, capabilities that will significantly extend knowledge on both fronts end LHC era. In this report we review revisit potential search, directly...
A bstract The soft bootstrap program aims to construct consistent effective field theories (EFT’s) by recursively imposing the desired limit on tree-level scattering amplitudes through on-shell recursion relations. prime example is leading two-derivative opera tor in EFT of SU( N ) x )/SU( nonlinear sigma model (NLSM), where 𝒪(p 2 with an arbitrary multiplicity external particles can be soft-bootstrapped. We extend 4 operators and introduce “soft blocks,” which are seeds for bootstrap....
We obtain for the first time all quadratic-in-spin interactions in spinning binaries at third subleading order post-Newtonian (PN) gravity, and provide their observable binding energies gauge-invariant relations to angular momentum. Our results are valid generic compact objects, orbits, spin orientations, enter fifth PN maximally-rotating thus pushing state of art. This is accomplished through an extension effective field theory gravitating its computational application. also discover a new...

We investigate the existence of double copy structure, or lack thereof, in higher derivative operators for Nambu-Goldstone bosons. At leading $\mathcal{O}({p}^{2})$, tree amplitudes bosons adjoint representation can be (trivially) expressed as itself and cubic biadjoint scalar theory, through Kawai-Lewellen-Tye bilinear kernel. next-to-leading $\mathcal{O}({p}^{4})$ there exist four general, among which we identify one operator whose exhibit flavor-kinematics duality written...
We present universal relations between entanglement entropy, which quantifies the quantum correlation subsystems, and cross section, is primary observable for high-energy particle scattering, by employing a careful formulation of wave packets incoming particles. For 2-to-2 elastic scattering with no initial subdividing system along labels, we show that both Rényi Tsallis entropies in final states are directly proportional to section units transverse size packets, then interpreted as...
We present a Ward identity for nonlinear sigma models using generalized shift symmetries, without introducing current algebra or coset space. The constrains correlation functions of the model such that Adler's zero is guaranteed S-matrix elements, and gives rise to subleading single soft theorem valid at quantum level all orders in Goldstone decay constant. For tree amplitudes, leads novel Berends-Giele recursion relation as well an explicit form factor. Furthermore, interactions cubic...
Nonlinear sigma model (nlσm) based on the coset SU(N)×SU(N)/SU(N) exhibits several intriguing features at leading O(p2) in derivative expansion, such as flavor-kinematics duality and an extended theory controlling single triple soft limits. In both cases cubic biadjoint scalar plays a prominent role. We extend these two directions. First we uncover new for SO(N+1)/SO(N) nlσm O(p2), which is bifundamental/biadjoint theory. Next provide evidence dualities up to O(p4) SU(N) SO(N) nlσm's....
A large class of models addressing the electroweak naturalness problem postulates existence new spontaneously broken global symmetries above weak scale. The Higgs boson arises as a pseudo-Nambu-Goldstone (pNGB) whose interactions are nonlinear due to presence de- generate vacua. We argue that, once normalization pNGB decay constant f is determined, in gauge sector universal infrared and independent symmetry breaking pattern G/H, even after integrating out heavy composite resonances. propose...
We study the three-particle and four-particle scattering amplitudes for an arbitrary, finite number of massive scalars, spinors vectors by employing on-shell spinor formalism. consider most general with energy-growing behavior at $\mathcal{O}(E)$. This is special case requirement tree unitarity, which states that $N$-particle level should grow as $\mathcal{O}({E}^{4\ensuremath{-}N})$ in high-energy hard-scattering limit, i.e., fixed nonzero angles. Then factorizable parts are calculated...
A bstract The construction of effective actions for Nambu-Goldstone bosons, and the nonlinear sigma model, usually requires a target coset space G / H . Recent progresses uncovered new formulation using only IR data without reference to broken group in UV, by imposing Adler’s zero condition, which can be seen originate from superselection rule degenerate vacua. imposes shift symmetry on Lagrangian enforce correct single soft limit amid constraints unbroken We present systematic study...
A bstract We initiate a phenomenological study of “universal relations” in composite Higgs models, which are dictated by nonlinear shift symmetries acting on the 125 GeV boson. These relations among one couplings with two electroweak gauge bosons (HVV), Higgses (HHVV), three (HVVV), as well triple boson (TGC), all controlled single input parameter: decay constant f pseudo-Nambu-Goldstone Assuming custodial invariance strong sector, relation is independent symmetry breaking pattern UV, for an...
A bstract We generalize soft theorems of the nonlinear sigma model beyond $$ \mathcal{O} <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mi>O</mml:mi></mml:math> ( p 2 ) amplitudes and coset SU( N × / ). first discuss universal flavor ordering for Nambu-Goldstone bosons, so that we can reinterpret known single theorem in context a general symmetry group representation. then investigate special case fundamental representation SO( ), where “pair basis” is available. provide novel...
Exceptional theories are a group of one-parameter scalar field with (enhanced) vanishing soft limits in the S-matrix elements. They include nonlinear sigma model (NLSM), Dirac-Born-Infeld scalars and special Galileon theory. The behavior results from shift symmetry underlying these theories, which leads to Ward identities generating subleading single theorems as well novel Berends-Giele recursion relations. Such an approach was first applied NLSM 1709.08639 1804.08629, here we use it...
The scattering cross section is the effective area of collision when two particles collide. Quantum mechanically, it a measure probability for specific process to take place. Employing wave packets describe process, we compute entanglement entropy in 2-to-2 general setting using $S$-matrix formalism. Applying optical theorem, show that linear $\mathcal{E}_2$ given by elastic $\sigma_{\text{el}}$ unit transverse size $L^2$ packet, $\mathcal{E}_2 \sim \sigma_{\text{el}}/L^2$, initial states...
