One of the important concepts that governs the amplitude and phase of energy transmission is impedance. The other is the concept of geometric wavefunction that arises from geometric algebra. While Pauli sigma matrices form the basis of space in 3D, the Dirac matrices are basis vectors of space-time in the geometric representation. Wavefunction interactions are modeled by geometric products,...

The clockwork mechanism is a relatively new mechanism to generate suppressed couplings in a theory containing no small parameters. We develop a new class of clockwork theories with an augmented structure of the near-neighbour interactions along a one-dimensional closed chain. Such a topology leads to new and attractive features in addition to generating light states with hierarchical couplings...

We propose an E8⊗E8 unification of the standard model with pre-gravitation, on an octonionic space (i.e. an octonion-valued twistor space equivalent to a 10D space-time). Each of the E8 has in its branching an SU(3) for space-time and an SU(3) for three fermion generations. The first E8 further branches to the standard model SU(3)c⊗SU(2)L⊗U(1)Y and describes the gauge bosons, Higgs and the...

The fundamental nature of neutrinos, whether they are Dirac or Majorana fermions, is still unknown and has been an open question for long time. If we consider neutrinos to be Majorana type, then the two flavour neutrino mixing matrix contains a Majorana phase. However, this phase doesn't appear in neutrino oscillation probabilities for vacuum as well as for matter modified oscillations. This...

The nature of neutrinos, whether Dirac or Majorana, is hitherto unknown. Assuming neutrinos to be Dirac, which needs $B-L$ to be an exact symmetry, we make an attempt to explain the observed proportionality between the relic densities of dark matter (DM) and baryonic matter in the present Universe ${\it i.e.,}\,\, \Omega_{\rm DM} \approx 5\, \Omega_{\rm B}$. Assuming the existence of heavy...

After a decade of the discovery of Higgs boson the direct search for new particles has put an energy gap between the SM and new physics. In this scenario the framework of effective field theory is the ideal one for going forward. Nowadays its a common practice to explain deviations from SM predictions by incorporating effective operators. We can treat the SM as an effective theory by adding...

Why is there something instead of nothing? Every particle in nature has it's corresponding antiparticle.In theory as well as in experiments it is seen that particle antiparticle always comes in pairs.Yet we only observe matter in our everyday environment.So does our universe fundamentally favours matter over antimatter?

Galactic cosmic rays are deflected by the Sun’s magnetic field, leading to significant energy-dependent temporal and spatial variations in their intensity. The muons observed at GRAPES-3 arise from extensive air showers as cosmic ray secondaries originating in the interactions of these cosmic rays with the upper atmosphere. We observe strong correlations between the muon flux measured by...

We have studied weak pion production off the nucleon induced by (anti-) neutrino. The model is built by taking the contribution from non-resonant background terms and the dominant $\Delta(1232)$ resonance. We also include higher resonances(four-star in PDG) such as $P_{11}(1440)$, $D_{13}(1520)$, $S_{11}(1535)$, $S_{11}(1650)$ and $P_{13}(1720)$, which helps us to extend the model to higher...

In this work, we study the phenomenological effects of an eV-scale sterile neutrino in neutrinoless double beta decay and active neutrino masses and mixings. We use $A_4 \times Z_4$ discrete symmetry extension of Standard Model to develop a model of neutrino masses and mixings in 3+1 scheme within the Minimal Extended Seesaw mechanism. We consider an $A_4$ triplet right-handed neutrino N and...

Neutrino physics gives us an opportunity to investigate new physics beyond the standard model. Recent data from the two long-baseline accelerator experiments, NO$\nu$A and T2K, appear to show some discrepancy in the standard 3-flavor scenario. Here, we intend to explore the next generation of long-baseline neutrino experiments T2HK and DUNE. We study the sensitivities of the non standard...

According to General Relativity spacetime is curved in the presence of matter. Einstein-Cartan theory is a simple extension of GR where the spin of the matter also affects the curvature of spacetime. This new structure of spacetime requires an affine connection which is no longer torsionless. So, the connection becomes an independent variable alongside the metric. If we want to include...

Over the past ten years, the evidence for charmed mesons has increased rapidly and remarkably in comparison to the bottom mesons [1]. In the bottom sector, however, it is challenging to identify the broad resonance states because of large non-resonant continuum contributions. To date, the experimental groups have confirmed only ground and low-lying excited states of bottom mesons [2-4]. In the...

We present a study of contributions from non-perturbative (NP) effects which include multi-parton interactions (MPI), and hadronization effects in Monte Carlo (MC) event generator HERWIG7 for dijet final states in proton-proton collisions at √s = 13 TeV. As the most precise higher-order predictions of perturbative Quantum Chromodynamics (pQCD) usually do not account for such effects, these...

The discovery of neutrino oscillations i.e. the discovery of neutrino mass, and progress of other experimental observations motivate us to develop models that can address multiple beyond Standard model issues that can be tested using present and future experiments. One such economic model is Ma's Scotogenic model, which generates Majorana neutrino mass at the 1-loop level and includes a dark...

Non-topological solitons, of which Q-Balls are particular examples, are localised solutions in field theories which have finite energies. Q-Balls were first explored by Sidney Coleman back in 1985, and then extensively studied by others. Due to the non linearity in the equations of motion, it is very difficult to obtain analytical solution except in some limiting cases (thin and thick wall...

In this work we examine the model dependence of the stringent constraints on the gluino mass obtained from the Large Hadron Collider (LHC) experiments by analyzing the Run II data using specific simplified models based on several ad hoc sparticle spectra which cannot be realized even in the fairly generic pMSSM models. We first revisit the bounds on the gluino mass placed by the ATLAS...

In our previous work, we obtain a connection between ($0\nu\beta\beta$)-decay and DM. As a result, we get six hybrid textures, which reproduce correct low energy phenomenology....

In the Standard Model(SM), the physics of charm meson is not expected to have new physics(NP) discovery potential because the relevant CKM matrix elements $V_{cs}$ and $V_{cd}$ are well known, CP asymmetries and $D^{0}$-$\bar{D^0}$ oscillations are small. It has been pointed out that the c$\rightarrow$ u$\gamma$ decays might have some contributions from the non-minimal supersymmetry, which is...

LHC Run-I and RUN-II data highly constrain masses of electroweakinos in R-parity conserved (RPC) scenarios through various final states usually associated with large missing energy. In R-parity violating (RPV) scenarios the situation may differ depending on various RPV decay modes of the lightest supersymmetric particle. Trilinear RPV coupling term ($\lambda_{ijk}L_i.L_je_k^c$) allows the...

Strangeness enhancement in high-energy heavy-ion collisions remains a key signature to identify the formation of Quark-Gluon Plasma (QGP) in such collisions. The study of strange hadrons and resonances may provide valuable information about the strongly interacting matter produced in heavy-ion collisions.
