May the four be with you: Novel IR-subtraction methods to tackle NNLO calculations

W. J. Torres Bobadilla, G. F. R. Sborlini, P. Banerjee +21

In this report, we present a discussion about different frameworks to perform precise higher-order computations for high-energy physics. These approaches implement novel strategies…

Testing the dark SU(N) Yang-Mills theory Confined Landscape: From the Lattice to Gravitational Waves

Wei-Chih Huang, Manuel Reichert, Francesco Sannino +1

We pave the way for future gravitational-wave detection experiments, such as the Big Bang Observer and DECIGO, to constrain dark sectors made of SU(N) Yang-Mills confined theories.…

IceCube constraints on Violation of Equivalence Principle

Damiano F. G. Fiorillo, Gianpiero Mangano, Stefano Morisi +1

Among the information provided by high energy neutrinos, a promising possibility is to analyze the effects of a Violation of Equivalence Principle (VEP) on neutrino oscillations. W…

Cosmic antihelium-3 nuclei sensitivity of the GAPS experiment

N. Saffold, T. Aramaki, R. Bird +52

The General Antiparticle Spectrometer (GAPS) is an Antarctic balloon experiment designed for low-energy (0.10.3 GeV/) cosmic antinuclei as signatures of dark matter annihilat…

Taming the in Little Randall Sundrum Models

Giancarlo D'Ambrosio, Mathew Thomas Arun, Ashwani Kushwaha +1

The Randall Sundrum (RS) models receive significant constraints from the neutral Kaon system. The CP violating observable , in Randall Sundrum scenario, requires the lightest…

Polarization as an Additional Constraint on New Physics in the Transition

Mikhail A. Ivanov, Jürgen G. Körner, Pietro Santorelli +1

Measurements of the branching fractions of the semileptonic decays and systematically exceed the Standard Model (SM) predictions, pointi…

Chiral oscillations in the non-relativistic regime

Victor A. S. V. Bittencourt, Alex E. Bernardini, Massimo Blasone

Massive Dirac particles are a superposition of left and right chiral components. Since chirality is not a conserved quantity, the free Dirac Hamiltonian evolution induces chiral qu…

A New Extraction of Pion Parton Distributions in the Statistical Model

Claude Bourrely, Franco Buccella, Jen-Chieh Peng

We present a new analysis to extract pion's parton distribution functions (PDFs) in the framework of the statistical model. Starting from the statistical model framework first deve…

Fully exclusive heavy quark-antiquark pair production from a colourless initial state at NNLO in QCD

Gábor Somogyi, Francesco Tramontano

We present a local subtraction scheme for computing next-to-next-to-leading order QCD corrections to the production of a massive quark-antiquark pair from a colourless initial stat…

Observable features in (ultra)high energy neutrinos due to active-sterile secret interactions

Damiano F. G. Fiorillo, Stefano Morisi, Gennaro Miele +1

We consider the effects of active-sterile secret neutrino interactions, mediated by a new pseudoscalar particle, on high- and ultra high-energy neutrino fluxes. In particular, we f…

Leptons in the Proton

Luca Buonocore, Paolo Nason, Francesco Tramontano +1

As is the case for all light coloured Standard Model particles, also photons and charged leptons appear as constituents in ultrarelativistic hadron beams, and admit a parton densit…

Lepton-quark collisions at the Large Hadron Collider

Luca Buonocore, Ulrich Haisch, Paolo Nason +2

Processes commonly studied at the Large Hadron Collider (LHC) are induced by quarks and gluons inside the protons of the LHC beams. In this letter we demonstrate that, since proton…

Gravitational Waves from Pati-Salam Dynamics

Wei-Chih Huang, Francesco Sannino, Zhi-Wei Wang

We show that it is possible to use gravitational wave detectors to observe the occurrence of a first order phase transition in Pati-Salam extensions of the Standard Model. We show…

Cosmogenic neutrino fluxes under the effect of active-sterile secret interactions

Damiano F. G. Fiorillo, Gennaro Miele, Stefano Morisi +1

Ultra High Energy cosmogenic neutrinos may represent a unique opportunity to unveil possible new physics interactions once restricted to the neutrino sector only. In the present pa…
