Status of light inflaton: from inflation to laboratory
Niloy Mondal, Shashwat Sharma, Mathew Thomas Arun +1
We investigate the viability of the light inflaton scenario in light of the latest inflationary constraints from the Atacama Cosmology Telescope (ACT), together with bounds from co…
From WIMP to FIMP during reheating: collider vs non-collider probes for p-wave annihilation
Dipankar Pradhan, Niloy Mondal, Abhik Sarkar +4
By examining the transition from freeze-out to freeze-in dark matter (DM) production within the framework of perturbative reheating, where DM interacts with the visible sector thro…
RG evolution and effect of intermediate new-physics on four-fermion operators
Mathew Thomas Arun, Shyam M, Ritik Pal
Motivated by the stringent experimental bounds on proton lifetime and the need for precise low-energy predictions, there has been renewed interest in the renormalization group (RG)…
Learning holographic QCD with unflavored meson spectra
Mathew Thomas Arun, Ritik Pal
We develop a data-driven neural network framework to reconstruct the five-dimensional background geometry, the dilaton potential, and the chiral-symmetry-breaking scalar potential…
On the role of cosmological constant in modeling hadrons
Mathew Thomas Arun, Nabeel Thahir
Einsteins gravity with a cosmological constant in four dimensions can be reformulated as a theory characterized solely by the dimensionless coupling ($G…
RG evolution and effect of intermediate new physics on six-quark operators
Mathew Thomas Arun, Shyam M, Ritik Pal
The recent identification of possible 11 neutron-antineutron (-) oscillation candidate events at Super-Kamiokande has renewed the interest in transitions. In t…
Light PIDM in Warped Extra Dimensions
Mathew T Arun, Prachiti P. Athalye, Basabendu Barman
Traditional Planckian Interacting Dark Matter (PIDM), which interacts exclusively through gravity, typically requires heavy DM candidates (with mass GeV) and very hi…
Constraining anti-baryonic dark matter through correlated nucleon decay signatures
Mathew Thomas Arun, Anuja Bandu Khadse
Baryon number violation in the visible sector induced by anti-baryonic dark matter provides a viable mechanism for low-scale baryogenesis. Two of the most sensitive probes of this…
Axi-Higgs portal Dark Matter via Wess-Zumino mechanism
Akshay Anilkumar, Mathew Thomas Arun, Arjun S. Nair
We study the axion portal between the visible and the dark sector, where the dark matter is charged under an abelian extension of the Standard Model. In general, such models are an…
Constraining SMEFT BSM scenarios with EWPO and
Mathew Thomas Arun, Kuldeep Deka, Tripurari Srivastava
Precision observables are well known for constraining most of the Beyond Standard Model (BSM) scenarios tightly. We present here a simple and comprehensive fitting framework for va…
Tri-bimaximal-Cabibbo Mixing: Flavour violations in the charged lepton sector
Mathew Thomas Arun, Anirudhan A. Madathil
The well understood structure of matrix mandates a Cabibbo mixing matrix in the first two generations of the charged lepton sector if we assume Tri-bimaximal mixing in t…
Assisted baryon number violation from dimensions
Akshay A, Mathew Thomas Arun
Proton decay in six dimensions orbifolded on square is highly suppressed at tree-level. This is because baryon number violating (BNV) operators containing only the zero m…
Neutron oscillation and Baryogenesis from six dimensions
Mathew Thomas Arun, Debajyoti Choudhury
Considering a six-dimensional geometry orbifolded on with quarks and leptons localised on orthogonal branes, we show that the construction admits observable…
Restricting operators from
Mathew Thomas Arun, Priyanka Lamba, Sudhir K. Vempati
In this paper we consider semileptonic lepton flavor violating operators of the type in low energy effective theory (LEFT). At the chiral scale, we match these operators t…
Baryon number violation from confining New Physics
Mathew Thomas Arun
The detection of neutron-antineutron oscillation will be a discovery of fundamental importance in particle physics and cosmology. In models discussed widely in literature, the proc…
Search for the boson decaying to a right-handed neutrino pair in leptophobic models
Mathew Thomas Arun, Arpan Chatterjee, Tanumoy Mandal +3
The extensions of the Standard Model contain a heavy neutral gauge boson . If leptophobic, the boson can evade the stringent bounds from the dilepton resonance sea…
Flavour violating charged lepton decays in Little Randall-Sundrum Model
Akshay A, Mathew Thomas Arun
The Little Randall-Sundrum (Little RS) model receives significantly stronger constraints from the flavour observables in comparison to Randall-Sundrum (RS) model. In this paper, we…
Testing left-right symmetry with an inverse seesaw mechanism at the LHC
Mathew Thomas Arun, Tanumoy Mandal, Subhadip Mitra +3
In the left-right symmetric models, a heavy charged gauge boson can decay to a lepton and a right-handed neutrino (RHN). If the neutrino masses are generated through the stand…
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…
Relaxing the constraint on compactified extra-dimension
Mathew Thomas Arun
It has been known for some time that the inclusion of brane fluctuations, namely branons, helps in the suppression of KK-mode couplings to brane localised matter fields. In this pa…
Living Orthogonally: Quasi-universal Extra Dimensions
Mathew Thomas Arun, Debajyoti Choudhury, Divya Sachdeva
The minimal Universal Extra Dimension scenario is highly constrained owing to opposing constraints from the observed relic density on the one hand, and the non-observation of new s…
Universal Extra Dimensions and the Graviton Portal to Dark Matter
Mathew Thomas Arun, Debajyoti Choudhury, Divya Sachdeva
The Universal Extra Dimension (UED) paradigm is particularly attractive as it not only includes a natural candidate for the Dark Matter particle but also addresses several issues r…
Bulk gauge and matter fields in nested warping: II. Symmetry Breaking and phenomenological consequences
Mathew Thomas Arun, Debajyoti Choudhury
Generalizing the Randall-Sundrum scenario to higher dimensions with nested warpings has been shown to avoid the constraints besetting the former. In the first paper of this series…
Gravitons in multiply warped scenarios - at 750 GeV and beyond
Mathew Thomas Arun, Pratishruti Saha
The search for extra dimensions has so far yielded no positive results at the LHC. Along with the discovery of a 125 GeV Higgs boson, this implies a moderate degree of fine tuning…
