Event Details

Overview

The SHEAP 2026 is an intensive academic program hosted by the Institute for Fundamental Study (IF), Naresuan University. The school aims to provide a comprehensive bridge for advanced undergraduate and graduate students into the frontiers of High-Energy Physics and Astrophysics, focusing on the mathematical structures and physical implications of modified gravity.

Registration Information

The school welcomes undergraduate seniors and graduate students (Master's and Ph.D.) with a strong interest in theoretical physics.

  • Aspect Capacity: 30 participants - (The list of selected participants will be announced later for confirmation.)
    Registration Fee: Free! (No cost to join the activity.)
  • Travel Expenses: Participants are responsible for their own travel costs. We have some travel support for foreign students in ASEAN. This support is limited to 4-5 students, depending on our budget. 

  • Accommodation: We support free on-campus accommodation at Naresuan dormitory for all students.  https://maps.app.goo.gl/SqeMhnvrxy5SNofv6.  This is available upon request. 
    (If you want to stay at a different place, you will be responsible for booking and covering the lodging costs yourself.)

    • Stay period: From the night of August 12 – 19, 2026.

    • Room Format: Shared rooms with other participants (2 people per room, separated by gender).

  • Please provide your information for registration in the following link https://forms.gle/oTNTQm4saHDwFQqH6

Objectives

  • Foundation Building: To provide rigorous training in General Relativity, Field Theory, and Constraint Analysis.

  • Advanced Expertise: To introduce students to modern theories of gravity (Horndeski, DHOST, MMG) and Effective Field Theory (EFT).

  • International Collaboration: To facilitate knowledge exchange between Thai students and world-class experts from international institutions.

Scientific Scope & Key Topics

  • Fundamental Reviews: Review of GR, Field Theory, Cosmology, and Constraint Analysis.

  • Mathematical Foundations: Stability and Causality in gravity, and the Cauchy problem in modified gravity theories.

  • Modern Gravity Theories: Scalar-Tensor theory, Horndeski theory, GLPV theories, DHOST, U-DHOST, and Minimal Modified Gravity (MMG).

  • Effective Field Theory (EFT): Goldstone Bosons, EFT of Inflation, Dark Energy, and its applications in modern physics.
